Question

6. The perimeter of a square is double that of a rectangle. If perimeter of the
square is 120 m, and length and breadth of the rectangle are in the ratio 3:2,
find the breadth of the rectangle.​

Answer 1

Answer:

12 m

Step-by-step explanation:

Let the lenght and breadth be 3x and 2x respectively.

Perimeter of rectangle = 120/2

= 60 m

60 = 2(3x + 2x)

60/2 = 5x

30 = 5x

x = 30/5

x = 6

breadth = 2x = 2*6 = 12m
