Perimeter=(2*length)+(2*width)
length=2*w
132=(2(2w))+(2w)
132=(4w)+(2w)
132=6w
w=22
l=44

I will not give you the answer but I will show you how to solve this.

55*.6= A
65*.6=B
75*.6=C
85*.6 = D

Do you see the trend? Continue until ten equations are formed and add all of the totals. A+B+D+C...=Total
