A neighbor gave her 30 feet of fencing, and melody wants the length of the garden along the garage to be 3 feet more than the width. what is the length of the garden? write your answer without units.

Respuesta :

Width = w
Length = w + 3
Perimeter of Rectangle = 2Width + 2Length

2w + 2l = 30
2w + 2(w+3) = 30
2w + 2w + 6 = 30
4w + 6 = 30
4w = 24
w = 24/4 = 6

length = w + 3 = 6 + 3 = 9

length = 9
