Problema Solution
Mary has a rectangular vegetable garden in her back yard with 160 feet of fence around it. The length of the garden is 9 times as long as the width, what are the dimensions of the garden?
Answer provided by our tutors
let 'w' represent the width, then '9w' represents the length
a fence of 160 feet indicates a perimeter of 160 feet
perimeter = 2(l+w), where 'l' and 'w' are length and width, respectively
160 = 2(w+9w)
80 = 10w
w = 80/10 = 8
9*8 = 72
the width of the garden is 8 feet, the length of the garden is 72 feet
