The area of a square is 144 m². Find its perimeter.
Choose the correct choice from the following answers:
A) 18 m B) 28 m C) 38 m D) 42 m E) 48 m

Rationale: area of square = side × side given ; area of square = 144 m ² therefore , side ² = 144 m ² therefore , side = √ ( 144 m ² ) = √ ( 2 × 2 × 2 × 2 × 3 × 3 ) m ² = 2 × 2 × 3 m = 12 m now , the perimeter of the square = 4 x side = 4 × 12 m = 48 m answer : e
Answer: E
