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

$\huge\mathfrak{Solution:}$

Given that:

• Perimeter of square park = 320m

To find:

• The area of square park

We know that,

$\boxed{Perimeter\: of \:square \:= 4 × side}$

$\implies$ 4 (side)= 320.

Side = $\cancel\dfrac{320}{4}$= 80.

Now,

$\underline{Using\:the\:formula}$

Area of square = (side)^2

$\implies$ 80^2= 6400.
