Perimeter of a rectangle = 2l + 2b

where

l = length

b = breadth

The length is twice it's breadth which is written as

l = 2b

Perimeter = 2(2b) + 2b

72 = 4b + 2b

72= 6b

Divide both sides by 6

b = 12 meters

Since l = 2b

l = 2(12) = 24 meters

The length of the rectangle is 24 meters and it's breadth is 12 meters

Hope this helps
