Question

The length and breadth of a rectangle are in the ratio `3:2`. The perimeter of the rectangle is 10 cm, then its length is
A. 2
B. 5
C. 3
D. 4

Answer 1

Correct Answer - C
Given `l:b=3:2`
Let `l=3x,b=2x`
Perimeter of the rectangle `=2(3x+2y)=10x`
`therefore 10x=10`
`x=1`
`therefore` "Length"` =3x=3xx1=3cm`
Hence, the correct option is (c).
