विकल्प

• 24 cm

• 36 cm

• 48 cm

Answer 1

Area of a square is 144 cm². Its perimeter is 48 cm.

Explanation:

The area of a square is given by the formula:

Area = Side²

Given the area is 144 cm²,

Side = `sqrt(144)` = 12 cm

The perimeter (P) of a square is:

P = 4 × side

= 4 × 12

= 48 cm

Therefore, the perimeter is 48 cm.
