find the perimeter of a square whose area is 144

➸We already know that 144 is 12×12, but if you didn't know you could do √144 on your calculator and get 12. Since each side is 12, we multiply 12 by 4, giving us 48 feet as our perimeter.

Answer 2

Area of a square = 144cm²

side × side = 144

side² = 144

side = √144

side = 12cm

Perimeter of square = 4 × side

= 4 × 12

= 48cm
