✯ Question :-

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

✯ Concept :-

• There is a square park whose perimeter is 320 and where to find the area. For finding the area for chef to work out the length after square by using the formula of perimeter then we can work out the area.

✯ Solution :-

★ Perimeter = 4a★

⇒320 m = 4a

⇒320/4 = a

⇒80 = a

Therefore, the length of the square is 80 m.

✯ Area :-

★ Area = a² ★

⇒Area = 80²

⇒Area = 6400 cm²

Therefore, the area of the square park is 6400 cm².
