The perimeter of a square is 220 centimeters. Find its area.

Answer 1

Given that the perimeter of the square = 220 cm.

We know that the perimeter of a square = 4 × side of the square.

⇒ 220 cm = 4 × side of the square

⇒ Side of the square = cm

= 55 cm

Now, area of the square = (side) ²

= 55² cm²

= (5 × 11)² cm²

= 5² × 11² cm²

= 25 × 121 cm²

= 3025 cm²

Thus, the area of the square is 3025 cm².
