P = perimeter
P = 54 in.
P = 2(L+W), where L=Length and W=Width
.
L = W+3
.
substitute
.
2(W+3) + 2W = 54
.
2W +6 +2W = 54
.
4W = 48
.
W = 12
.
L = W+3
L = 12+3
L = 15
.
Check the perimeter to be sure this solution is the answer.
.
2L = 2(15) = 30
2W = 2(12) = 24
30+24 = 54
Correct.
.
Answer: Length = 15 inches; Width = 12 inches.
