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

A square has four equal sides. The perimeter of a square equals 4 times its side length, whereas the area of a square equals the square of its side length.

Answer: The area of a square park whose perimeter is 320 m is 6400 m².

Let's find the side of the square using the perimeter formula and then the area.

Explanation:

Given : Perimeter of the square park = 320m

We know that,

Perimeter of a square = 4 × side

⇒ 4 × side = 320

⇒ side = 320/4

⇒ side = 80m

Area of a square = side²

Hence, Area of the square park = 80² = 80 × 80 = 6400m²

Thus, the area of a square park whose perimeter is 320 m is 6400m².
