Question

Find the perimeter and the area of the square ABCD, if its one side equals
(1) 30 cm
(2) 22 cm
(3) 1.8 cm
(4) 3.7 cm

Answer 1

The perimeters are 120 cm, 88 cm, 7.2 cm, 14.8 cm and areas are 900 cm², 484 cm², 3.24 cm², 13.69 cm² respectively.

Step-by-step explanation:

1) Side of square ABCD = 30 cm

Perimeter = 4 x 30 = 120 cm

Area = 30² = 900 cm²

2) Side of square ABCD = 22 cm

Perimeter = 4 x 22 = 88 cm

Area = 22² = 484 cm²

3) Side of square ABCD = 1.8 cm

Perimeter = 4 x 1.8 = 7.2 cm

Area = 1.8² = 3.24 cm²

4) Side of square ABCD = 3.7 cm

Perimeter = 4 x 3.7 = 14.8 cm

Area = 3.7² = 13.69 cm²

Hence, the perimeters are 120 cm, 88 cm, 7.2 cm, 14.8 cm and areas are 900 cm², 484 cm², 3.24 cm², 13.69 cm² respectively.
