Question

perimeter of a rectangular plot is 200m .its length is 4 times of its breadth. find the breadth.

Answer 1

heya

here is your answer

A.T.Q.

let b= x

so length = 4x

p = 200m

so, 2×(4x+x) = 200

=> 5x = 200/2 = 100

=> x = 100/5 = 20

hope it helps

Answer 2

Perimeter =2(l+b)
=200=2(l+b)
As length is 4 times of its breadth
so length = 4l
breadth = l
200=2(4l+l)
200=2(5l)
200=10l
l=200/10
l=20m
Breadth will be 20/4 = 5m
