how do you calculate square metres?

Answer 1

The question seems incomplete. You can elaborate by citing an example.

Answer 2

Square metres actually is a unit in mathematics. From wikipedia:
The square metre (also spelled meter, see spelling differences) is the SI derived unit of area, with symbol m². It is defined as the area of a square whose sides measure exactly one metre. The square metre is derived from the SI base unit of the metre, which in turn is defined as the length of the path travelled by light in absolute vacuum during a time interval of 1⁄299,792,458 of a second.
For different shapes, there are different ways of calculating the area of a certain surface. For example, for a four sided place you can calculate by multiplying the width with the length. The question now is what do you want to calculate? Square metres is only a unit.

Answer 3

I know you got a lot of answers but the approach here is a little different. The shape of an object decides whether you can use a simple formula or whether you need a graphical solution. For example, if the object is a square, a rectangle, a triangle, a circle etc., you have simple formulas to calculate the area. But to calculate the area of an irregular shape (like the country), you need to divide it into very small squares and count the full squares and half of the partially filled squares to arrive at an approximate value for the area. The smaller the graphical square compared to the object, the better will be the area value.

Answer 4

Square metres is the unit used for semi large areas. In order to find an area, you multiple the length and the width. (be sure that both length and width are in the same units).
i.e.
There's a square with a length of 5m.
5*5=25.
The area is 25 square metres.

I hope this is what you were asking.

Answer 5

You got your answer in the first one:

The square of any measurement is the length times the width or "height"

Horizontal measurement x the vertical measurement.

Therefore a field that is 10 metres long by ten metres wide is 100 square metres in size. Similarly a five metre long field which is five metres wide is 25 square metres in size

And a chalk square drawn on the wall which is one metre vertically and one metre horizontally is one square metre in size.

Answer 6

Length multiplied by width equals area squared.

Example. An area with a length of 2 metres and a width of 1 metre, equals 2 metres squared.

2m X 1m = 2m sq

Answer 7

Imagine you have a rectangle. One side measures 3 metres, the other side measures 2 metres. All you do is multiply the two numbers...so 3 x 2 = 6 the answer is 6 sq. metres.

Answer 8

That depends.. if the area is a perfect square like a square or a rectangle.. you measure the length by the breath.

..if the area is a equilateral triangle, it will be half of the base of the triangle multiplied by the perpendicular height.

..there are other equations depending on the shape of the are you wish to calculate.. like a circle or various polygons with various other properties.

Answer 9

the length multiplied by the width equals square metres

Answer 10

normally square meters are calculated for areas
this is meant by
multiple of any two distances you will get an area which is in square units

if the units are in meters then the result is square meters

Answer 11

the square meters in the sence, the calculation of area. the formula for the area calculation is length is multiplied by breadth. remember, the values or the both length and breadth should be in meters.
