Problema Solution
The perimeter of a rectangular oceanfront lot is 190 m. The width is one-fourth of the length. Find the dimensions.
Answer provided by our tutors
let
l = the length
w = the width
P = 190 m the perimeter
P = 2(l + w) is the perimeter of the rectangle thus we have:
2(l + w) = 190 divide both sides by 2
l + w = 95
the width is one-fourth of the length:
w = (1/4)l
by solving the system of equations:
l + w = 95
w = (1/4)l
we find:
l = 76 m
w = 19 m
