Question

Find the area of a square park whose perimeter is 320 m.

Answer 1

Given, perimeter of a square park = 320 m
We know that, perimeter of square = 4 x side
$\Rightarrow$ $4\times side=320$
$\Rightarrow$ $side=\frac{320}{4}=80m$
Also, area of a square = side $\times$ side
$\therefore$ Area of square park = 80 x 80
= 6400 $m^2$
Thus, the area of square park is 6400 $m^2$.
