Question

The length and breadth of a rectangular field are in the ratio of 3 : 2. If the perimeter of the field is 80m, its breadth (in metres) is :

• A. 18
• B. 16
• C. 10
• D. 24

Answer 1

Answer:

B. 16

Let length be 3x and breadth be 2x

Perimeter = 2 (length + breadth)

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

According to question,

10x = 80m

x = 8m

Breadth = 2x = 2× 8 = 16 m
