Problema Solution
The length of a rectangular banner is 5 feet longer than its width. If the area is 66 square feet, find the dimensions.
Answer provided by our tutors
Let
'l' = the length of the rectangle (rectangular banner)
'w' = the width of the rectangle (rectangular banner)
A = w*l = the area of the rectangle
l = w + 5
w*l = 66
By solving this system of equations we find 2 solutions but only consider the positive one since l>0 and w>0
l = 11 feet
w = 6 feet
the length is 11 feet.
the width is 6 feet.
