Problema Solution
If 90 feet of fencing is required to enclose a rectangular service yard whose width is two thirds is length , what are the dimensions of the yard?
Answer provided by our tutors
let
w = the width of the rectangular service yard and w>0
l = the length of the rectangular service yard and l>0
width is two thirds is length
w = (2/3)*l
90 feet of fencing is required to enclose a rectangular service yard
2*(w + l) = 90
by solving the system of equations
w = (2/3)*l
2*(w + l) = 90
we find
l = 27 ft
w = 18 ft
the dimensions of the yard are 27 ft and 18 ft.
