Question

The length of the breadth is twice it's breadth . If the perimeter is 72 cm , then find the length and breadth ?

Answer 1

W=breadth; L=length=2W P=perimeter=2(L+W)=72m

P=2(L+W)

72m=2(L+W) Divide each side by 2

36m=L+W Substitute for L

36m=2W+W

36m=3W Divide each side by 3.

12m=W ANSWER 1: The breadth is 12 meters.

L=2W=2(12m)=24m ANSWER 2: The length is 24 meters.

CHECK:

P=2(L+W)

72m=2(24m+12m)

72m=2(36m)

72m=72m
