Question

e) Area of a square whose perimeter is 40 m is?​

Answer 1

Step-by-step explanation:

perimeter= 4 into side

side =perimeter/4

side will be 10

area =side*side

I. e. 10*10=100

Answer 2

Given: The perimeter of a square is $40$m.

We have to find the area of the square.

We are solving in the following way:

As we know that the perimeter of a square is calculated by: $P=4a$

where, $a=side$

We have,

$=>P=4a\\=>40=4a\\\\=>\frac{40}{4} =a\\\\=>a=10m.$

Hence, the side of the square is $10m.$

We know that,

The area of the square $=side^{2}$

$=>A=10^{2} \\=>A=100m.sq.$

Hence, the area of the square will be$100m.sq.$
