Answer 1

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 24 cm.

Explanation:

Given, side of a square garden = 30 m

∵ Perimeter of a square = 4 × side

∴ Perimeter of a square garden = 4 × 30 m = 120 m

Scale used to draw it picture = 1 cm : 5 cm

Hence, the perimeter of a square in the picture = `120/5` = 24 cm
