Problema Solution

The length of a rectangle is 9 in more than the width. The perimeter is 54 in. Find the length and the width of the rectangl

Answer provided by our tutors

let 'w' represent the width, then 'w+9' represents the length


perimeter = 2(length + width)


54 = 2(w+w+9)

54 = 4w + 18

4w = 36

w = 36/4 = 9


9+9 = 18


the width of the rectangle is 9 in, its length is 18 in
