Problema Solution
The width of a rectangle is two-third of its length. If the perimeter is 180m,find the dimensions of the rectangle.
Answer provided by our tutors
let
w = the width of the rectangle
l = the length of the rectangle
the width of a rectangle is two-third of its length
w = (2/3)l
the perimeter is 180 m
2(l + w) = 180 divide both sides by 2
l + w = 90
by solving the system of equations
w = (2/3)l
l + w = 90
we find
l = 54 m
w = 36 m
