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
