Hi Jordan,

1) Let length= l inch, width = (l+3) inch

Perimeter of a rectangle=2l +2w = 2l+2l +6= 38

4l = 32

l=8

width of a rectangle= l+3=11 inch

2) 1 dozen can =12 cans= $1.74

2 cans = $1.74/6 =$0.29

If i buy 2 cans = $0.33

saving would be $0.33-0.29=$0.04 for 2 cans.

for 1 can savings would be $0.02.

4 cans savings would be $0.08

12 cans .................= $0.24
