Question

The area of a square field is 100 m². Find its perimeter.

Answer 1

Step-by-step explanation:

Area of Square field 100 metre square

Let each side of square be a m

ATQ,(a)¢2^=100

a=√100

a=10

Perimeter=?

Perimeter of Square=4×a=4×10=40 m

Answer 2

The perimeter of square field is 40 m.

Explanation:

We know that :  Area of a square : A= (x)² , where x is the side of the square.

To find x , we take square root on both sides , we will get

$x=\sqrt{A}$ , where A = area of the square      (1)

We are given that : The area of a square field is 100 m².

Put A = 100 in (1) , we get

$x=\sqrt{100}=10$

So , the side of square field is 10 m.

Perimeter of square = 4(side) = 4(10)= 40 m

Hence, the perimeter of square field is 40 m.
