Answer:
- length: 27 inches
- width: 6 inches
Step-by-step explanation:
Let w represent the width of the rectangle. The perimeter is twice the sum of length and width so is ...
P = 2(L + w) . . . . . . equation for perimeter
66 = 2((5w-3) +w) . . . substitute the given values
33 = 6w -3 . . . . . . . divide by 2 and collect terms
36 = 6w . . . . . . . . . add 3
6 = w . . . . . . . . . . . .divide by 6
L = 33-6 = 27
The length is 27 inches; the width is 6 inches.
