The ratio of length and breadth of a rectangle is 3 : 2 respectively. The respective ratio of its perimeter and area is 5 : 9. What is the breadth of the rectangle in metres ?

6 M
8 M
9 M
13 M

Sol:

Let the length and breadth of the rectangle be 3x and 2x respectively

Then,

Perimeter = 2 (3x + 2x) = 10x

And,

Area = (3x × 2x) = 6x²

So, breadth = (2 × 3) m = 6 m
