Problema Solution
The length is twice its width Perimeter of the rectangle 42m what is the length and width
Answer provided by our tutors
let
l = the length of the rectangle
w = the width of the rectangle
the length is twice its width
l = 2w
perimeter of the rectangle 42m
2(l + w) = 42
by solving the system of equations
l = 2w
2(l + w) = 42
we find
l = 14 m
w = 7 m
