Problema Solution
perimeter is 210 ft. squared. the length is 3 ft less than 3 times the width
Answer provided by our tutors
let
l = the length
w = the width
P = 210 ft the perimeter of the rectangle
the length is 3 ft less than 3 times the width
l = 3w - 3
the formula for the perimeter is P = 2(l + w)
2(l + w) = 210
by solving the system of equations
l = 3w - 3
2(l + w) = 210
we find
l = 78 ft
w = 27 ft
