Answer»

Homework 21:-

(1) Area of the square = (Side)²

Area of the square = (25)² = 625cm²

Therefore, the area of the square is 625cm²

(2) Area of the square = (Side)²

Area of the square = (32)² = 1024m²

Therefore, the area of the square is, 1024m²

(3) Area of the square = (Side)²

Area of the square = (17)² = 289m²

Therefore, the area of the square is, 289m²

(4) Area of the square = (Side)²

Area of the square = (35)² = 1225dm²

Therefore, the area of the square is, 1225dm²

(5) Area of the rectangle = l × b

Area of the rectangle = 22 × 18 = 396cm²

(6) Area of the rectangle = 34 × 20 = 680cm²

(7) Area of the rectangular park = 15 × 9 = 135m²
