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

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

Step-by-step 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
