Problema Solution
The width of a rectangle garden is 12 feet longer than its length. If the area of the garden is 240 square feet, calculate the width of the garden.
Answer provided by our tutors
let
w = the width of the garden
l = the length of the garden
the width of a rectangle garden is 12 feet longer than its length
w = l + 12
the area of the garden is 240 square feet and the area = width*length
w*l = 240
by solving the system of equations
w = l + 12
w*l = 240
we find and consider only the positive solutions that is
w = 22.61 ft
the width of the garden is 22.61 ft.
