Question

Use the formula to determine the area of squares with side lengths of 3 cm, 10.5 cm, and π cm.

Answer 1

For length of side = 3 cm

Area of the square = 9 cm²

For length of side = 10.5 cm

Area of the square = 110.25 cm²

For length of side = π cm

Area of the square = 9.869 cm²

Explanation:

The area of a square is given as :

Area = Side²

therefore,

For length of side = 3 cm

Area of the square = ( 3 cm )² = ( 3 × 3 ) cm² = 9 cm²

For length of side = 10.5 cm

Area of the square = ( 10.5 cm )² = ( 10.5 × 10.5 ) cm² = 110.25 cm²

For length of side = π cm

Area of the square = ( π cm )²

= ( π × π ) cm²

= 3.14² cm² [π = 3.14]

= 9.869 cm²
