More about Square

General

The area is the magnitude of the geometric shape in two-dimensional space. It is used in mathematics, medicine, engineering and other sciences, for example, in calculating the cross section of cells, atoms, or pipes, such as blood vessels or tap pipes. In geography, the area is used to compare the sizes of cities, lakes, countries and other geographical objects. The population density calculations also uses the area. The population density is defined as the number of people per unit area.

Units

Square meters

The area is measured in the SI system in square meters. One square meter - square square, with one meter side.

Single square

A single square is a square with the parties to one unit. The unit square is also equal to one. In the rectangular coordinate system, this square is in coordinates (0.0), (0.1), (1.0) and (1,1). On the complex plane of the coordinate - 0, 1, i. and i.+1, where i. - imaginary number.

AR

AR or weaving, as a measure of the square, is used in the CIS countries, Indonesia and some other European countries, to measure small urban objects such as parks when hectare is too large. One AP is 100 square meters. In some countries, this unit is called otherwise.

Hectare

In hectares, real estate are measured, especially land plots. One hectare is 10,000 square meters. It is used since French revolutionand applied in the European Union and some other regions. As well as AR, in some countries hectare is called differently.

Acre

IN North America And Burma area is measured in acres. Hectares are not used there. One acre is 4046.86 square meters. Initially, Acre was determined as an area that a peasant with a harness from two oxes could have been plowed in one day.

Barne

Barna are used in nuclear physics to measure cross-section of atoms. One barne is equal to 10⁻² ⁸ square meters. Barne is not a unit in the SI system, but adopted to use in this system. One bar is approximate equal to Square The cross section of the core of uranium, which physicists in a joke called "huge, like barn." Barn in English "BARN" (pronounced Barn) and from the joke of physicists This word was the name of the unit of Square. This unit originated during the Second World War, and liked the scientist, because its name could be used as a code in correspondence and telephone conversations within the Manhattan project.

Calculation of Square

The area of \u200b\u200bthe simplest geometric shapes are found by comparing them with a square of the famous area. It is convenient because the square area is easy to calculate. Some formulas for calculating the area of \u200b\u200bgeometric shapes shown below are obtained in this way. Also for calculating the area, especially the polygon, the figure is divided into triangles, calculate the area of \u200b\u200beach triangle according to the formula, and then fold. The area of \u200b\u200bmore complex figures is calculated using mathematical analysis.

Formulas for calculating the area

• Square: Side in the square.
• Rectangle: Work of the parties.
• Triangle (known side and height): The work of the side and height (distances from this side to the edge), divided by half. Formula: A \u003d ½AHwhere A. - area, a. - side and h. - Height.
• Triangle (two sides and angle between them are known): The work of the sides and sinus of the corner between them, divided by half. Formula: A \u003d ½AB sin (α), where A. - area, a. and b. - Parties, and α - the angle between them.
• Equilateral triangle: side, squared, divided by 4 and multiplied by square root From three.
• Parallelogram: The work of the side and height measured from this side to the opposite.
• Trapeze: The sum of the two parallel sides, multiplied by height, and divided into two. Height is measured between these two sides.
• A circle: The product of the square of the radius and π.
• Ellipse: The product of the semi-axle and π.

Calculation of surface area

Find the surface area of \u200b\u200bsimple bulk figures, such as a prism, you can scan of this figure on the plane. The scan of the ball is so impossible to obtain. The surface area of \u200b\u200bthe ball is found using the formula, multiplying the square of the radius by 4π. From this formula it follows that the area of \u200b\u200bthe circle is four times less than the surface of the surface of the ball with the same radius.

Surface Square Some Astronomical Objects: Sun - 6.088 x 10) Square kilometers; Earth - 5,1 x 10⁸; Thus, the surface area of \u200b\u200bthe Earth is about 12 times less than the surface area of \u200b\u200bthe Sun. The surface area of \u200b\u200bthe moon is approximately 3.793 x 10 ° C for square kilometers, which is approximately 13 times less than the surface area of \u200b\u200bthe Earth.

Plan meter

The area can also be calculated using a special instrument - a planimeter. There are several types of this instrument, for example polar and linear. Also, the planimeters are analog and digital. In addition to other functions, it is possible to enter into digital plan meters, which facilitates the measurement of objects on the map. The plan meters the distance traveled around the perimeter of the object being measured, as well as the direction. The distance traveled by the plan meter parallel to its axis is not measured. These devices are used in medicine, biology, technician, and agriculture.

Theorem on the properties of the area

According to an isoperimetric theorem, of all figures with the same perimeter, the largest area of \u200b\u200bthe circle. If, on the contrary, compare figures with the same area, then the circle has the smallest perimeter. The perimeter is the sum of the lengths of the side of the geometric shape, or a line that denotes the boundaries of this figure.

Second on the Lake Square - Lake Top in North America. This is one of the lakes of the System of the Great Lakes; Its area is 82,414 square kilometers. The third in Square - Lake Victoria in Africa. It covers an area of \u200b\u200b69,485 square kilometers.

Irina, s. Urusovo, Lipetsk region We want to put the greenhouses, you need to make calculations. Tell me how many weave and square meters in 1 hectare?
If you specify the field area with a side of several kilometers, then the record of the measurement of the site will be very multi-digit and complex for the sound. Therefore, for measuring and writing very large-scale areas, it is more convenient to use such units of measurement as weaving and hectare. Let us try to calculate how many square meters is contained in hectare and how many across it is 1 hectare.

Square meter

Square meter is a unit of measuring area. Visually, you need to draw a square with a side of 1 m. The square of the square is 1 square meter (we consider 1 x 1 \u003d 1), hence the name.

Weaving

Weaving is also a unit of measuring areas. We present a square with a side of equal to 10 m. The area of \u200b\u200bthe saw is 100 mq (we consider 10 x 10 \u003d 100). Easy to remember: weave - one hundred square meters.

Hectare

Hectares The most popular unit of measurement in the agricultural sector. To calculate the hectare area, the square with a side of equal to 100 m is visually drawn. The hectare area is 10 000 mq (100 x 100 \u003d 10 000).
Thus, we obtain clearly compulsion of units:

1 hectare \u003d 100 acres \u003d 10 000 sq.

1 weaving \u003d 100 mq \u003d 0.01 hectares.

This online calculator helps to make calculation, definition and calculating land area in online mode. The presented program is able to properly prompt how to perform the calculation of the area land plots incorrect form.

Important! The area must approximately fit into the circle. Otherwise, the calculations will be not entirely accurate.

Indicate all the data in meters

A B, D A, C D, B C- The size of each side of the defense.

According to the data introduced, our program in online mode is calculated and determined by land area in square meters, hundreds and acres and hectares.

Methods for determining the size of the site manual method

To properly perform the calculation of the plot area, you do not need to use complex tools. We take wooden pegs or metal rods and install them in the corners of our site. Next, using a measuring tape measure, we determine the width and length of the defense. As a rule, it suffices to measure one width and one length, for rectangular or equilateral sections. For example, we have the following data: width - 20 meters and length - 40 meters.

Next, go to the calculation of the area of \u200b\u200bthe defense. With the correct form of the site, you can use geometric formula Definition of the area (s) of the rectangle. According to this formula, you need to multiply the width (20) for the length (40), that is, the product of the length of both sides. In our case, S \u003d 800 m².

After we have identified our area, we can define the amount of acres on the land plot. According to generally accepted data, in one hundred and 100 m². Next, with the help of simple arithmetic, we split our parameter s per 100. The finished result and will be equal to the size of the defense in the weave. For our example, this result is 8. Thus, we obtain that the area area is eight acres.

In the event that the territory of the land is very big, it is best to perform all measurements in other units - in hectares. According to generally accepted units of measurement - 1 hectare \u003d 100 acres. For example, if our land plot according to the obtained measurements is 10,000 m², then in this case its area is equal to 1 hectare or 100 hectares.

If your site is irregular, then in this case the amount of acres directly depends on the area. It is for this reason with online calculator You can correctly calculate the parameter S of the defense, and then delivering the result received by 100. Thus, you will receive calculations in the weave. This method provides the ability to measure the plots of complex forms, which is very convenient.

common data

The calculation of land area is based on classical calculations, which are performed according to the generally accepted geodesic formulas.

In total, several methods are available for calculating land area - mechanical (calculated according to plan with the help of dimensional pallet), graphic (determined by the project) and analytical (with the help of the area of \u200b\u200bthe area measured lines).

To date, the most accurate way is deservedly considered - analytical. Using this method, errors in calculations, as a rule, appear due to errors on the terrain of the measured lines. This method is also quite complicated if the boundaries of curvilinear or the number of angle on the plot more than ten.

A little easier by calculations is a graphic method. It is best used in the case when the boundaries of the site are presented in the form of a broken line, with a small amount of turns.

And the most affordable and easy way, and the most popular, but also at the same time the biggest error is a mechanical way. Using this method, you can easily and quickly calculate the area of \u200b\u200bland simple or complex shape.

Among the serious disadvantages of a mechanical or graphic method, the following, except for errors in measuring the site, is added when calculating the error is added due to the deformation of the paper or the error in the preparation of plans.

About, how many weave in one hectare And how to fully calculate all this, you will find out by reading the following material in the article. Collected high-quality information.

I think to anyone at least once in life will have to or hectares. Then you will be useful to find out how many weave in one hectare and how to calculate everything correctly.

The ability to translate acres into hectares or vice versa will be useful in different areas of activity: in construction, agricultural work, purchase and sale of plots.

How one hectare is calculated

Most often, the unit of measuring the area of \u200b\u200bthe agricultural land is precisely hectare. It can be visually imagined as a square 100 per 100 meters.

In this unit, the measurement usually shows the area of \u200b\u200blarge farm possessions, parks, reserves, etc.

The hectare area can be determined using non-hard mathematical actions.

S \u003d 100 * 100 \u003d 10 000 m 2

That is, in one hectare 10 thousand square meters.

No need to confuse it with a square kilometer, which is also used to measure quite large squares. One kilometer square is also a square, but with the parties in 1000 meters.

Generally accepted that if land plot has parties whose length is within from 100 to 1000 m, then the measurement unit takes the hectare.

How to measure the area of \u200b\u200bthe wrong form

We do not always need to measure and translate the area of \u200b\u200bthe land plot of the right form, what should be done if you have to work with trapezoidal or round territories.

If the land plot has a round shape, then apply the formula for counting the area of \u200b\u200bthe circle, is S \u003d N R 2, where N is the number Pi (3,14.), and R is a radius.

In the case when the plot is uneven, or it is too difficult to visually split to more simple figuresYou should contact specialists who use the necessary equipment and instruments to provide you with accurate information about the area and then can already be translated into the necessary units.

It is worth considering that experts count the square in square meters and rounded it up to 1 m 2.

To begin with, you need to explain what weave. One weave is a plot, sizes one hundred per service. That is, its area is 100 m 2. Weavers use if you need to measure a relatively small area, for example, under the summer building or garden.

By the ratio of the area of \u200b\u200bone hectare and one weave, you can find out the answer to the question, delivered at the beginning of the article.

10 000 m 2/100 m 2 \u003d 100

That is, in one hectare You can "accommodate" 100 hundred.

How to translate weave in hectares

Make it quite easily. Here you will use elementary mathematics. In order to translate weave in hectares, you need to fold the proportion. For example, you need to translate 27 acres in ha (hectares).

We already know that in one hectare - 100 acres, and, let's say X. (X) hectares - 27 acres. Then the proportion has the following form:

Respectively, H. \u003d 1 * 27/100. Eventually, X. Equally 0.27 hectares. This will be the area of \u200b\u200bthe site presented in hectares.

If you fear to allow an error, you can use special online convectors, which in a few seconds will translate weave to hectares, or vice versa.

In order to better remember how many across one hectare, the next drawing is for you:
