Problema Solution
A rectangular garden has 88 feet of fencing around it. The garden is 4 feet longer than it is wide. Find the dimensions of the garden.
Answer provided by our tutors
let
w = the width of the garden
l = the length of the garden
P = 2 (l + w) the perimeter of the garden
rectangular garden has 88 feet of fencing around it that is P = 88 ft
2(l + w) = 88
the garden is 4 feet longer than it is wide
l = w + 4
by solving the system of equations
l = w + 4
2(l + w) = 88
we find
l = 24 ft
w = 20 ft
the dimensions of the garden are 24 ft and 20 ft.
