Problema Solution
You are building a rectangular fence and you have 150 feet of total fencing. The length of your fence has to be 4 times the width. What are the fence's dimensions?
Answer provided by our tutors
let
l = the length of the fence
w = the width of the fence
the length of your fence has to be 4 times the width:
l = 4w
you have 150 feet of total fencing means:
2(l + w) = 150 divide both sides by 2
l + w = 75
by solving the system of equations
l = 4w
l + w = 75
we find
l = 60 in
w = 15 in

the length of the fence is 60 inches.
the width of the fence is 15 inches.
