Question

Length of a rectangle is 20cm more than its breath. If its perimeter is 100cm, find sides of rectangle

Answer 1

length 35cm
breadth 15cm

Answer 2

Let the breath be b
Given length= 20+b

Given perimeter =100cm
We know that perimeter = 2(l+b)
2(l + b) =100
l+b = 50
20+b+b=50
2b=30
b=15

breadth =15cm
length = 20cm
