Side of a square garden is 30 m. If the scale used to draw its picture is 1 cm : 5 m, the perimeter of the square in the picture is

Given, the side of a square = 30m

The formula for perimeter of the square = 4 × side

∴ the perimeter of the square = 4 × 30 = 120m

The scale used to draw its picture is 1 cm : 5 m

Hence the perimeter of a square =

= 24 cm
