Side of a square garden is 30 m. If the scale used to draw its picture is 1cm: 5m, the perimeter of the square in the picture is
(a) 20 cm
(b) 24 cm
(c) 28 cm
(d) 30 cm
Solution:
Given, the side of a square garden is 30 m.
The scale used to draw its picture is 1 cm : 5 m
We have to find the perimeter of the square in the picture.
Perimeter = sum of all sides
We know, perimeter of square = 4(side)
= 4(30)
= 120 m
Scale = 1 cm : 5m
Perimeter of square in the picture = 120 / 5
= 24 cm
Therefore, the required perimeter is 24 cm.
