Problema Solution
The length of a rectangular banner is 7 feet longer than its width. If the area is 78 square feet, find the dimensions
Answer provided by our tutors
let 'w' represent the width, then 'w+7' represents the length
area = length * width
78 = w(w+7)
solving for 'w' we have a positive value of w=6
6+7=13
the width is 6 ft, the length is 13 ft
