Problema Solution
A rectangle is 5 times as long as it is wide. If the area is 125 square feet, find its perimeter.
Answer provided by our tutors
let 'w' represent the width, then '5w' represents the length
area = length * width
125 = 5w * w
5w^2 = 125
w = sqrt(125/5)
w = sqrt(25)
w = 5
5*5 = 25
the width of the rectangle is 5 feet, its length is 25 feet
