The area of a square is 144 m². Find its perimeter.	Choose one.
A) 18 m B) 28 m C) 38 m D) 42 m E) 48 m
Area of square = side × side   Given; area of square = 144 m²   Therefore, side² = 144 m²   Therefore, side = √(144 m²) = √(2 × 2 × 2 × 2 × 3 × 3) m² = 2 × 2 × 3 m = 12 m   Now, the perimeter of the square = 4 x side = 4 × 12 m = 48 m   ANSW48 mR : 48 m
