Answer:
Width = 5 inches
Length = 13 inches
Step-by-step explanation:
Width = W
Length = W + 8
Perimeter = 2(Length) + 2(Width)
Substitute in known values
36 = 2(W+8) + 2(W)
Multiply
36 = 2W + 16 + 2W
Add
36 = 4W + 16
Subtract 16 from both sides of the equation
20 = 4W
Divide both sides of the equation by 4
W = 5
Width = 5 inches
Length = 5 + 8 inches = 13 inches
Hope this helps :)
