Problema Solution
the length of a rectangular region is 20 meters less than four times its width. if the perimeter of the region is 135 meters, fond the dimensions of the region.
Answer provided by our tutors
let
l = the length of the region
w = the width of the region
P = 135 m the perimeter
the length of a rectangular region is 20 meters less than four times its width
l = 4w - 20
the perimeter of the region is 135 meters
2(l + w) = 135
by solving the system of equations
l = 4w - 20
2(l + w) = 135
we find
l = 50 m
w = 17.5 m
