Problema Solution
A building in a city has a rectangular base. The length of the base measures 75 ft less than twice the width. the perimeter of this base is 780ft. what are the dimensions of the base
Answer provided by our tutors
let
l = the length of the base
w = the width of the base
length of the base measures 75 ft less than twice the width
l = 2w - 75
the perimeter of this base is 780 ft
2(l + w) = 780
by solving the system of equations
l = 2w - 75
2(l + w) = 780
we find
l = 235 ft
w = 155 ft
