X=2.00+15x
2.75=2.00+15x
-2.00 -200
75=15x
Divide each side by 15
x=5

Answer
Perimeter of rectangle, P = 2L + 2W
P = 36ft
Width, W
Length, L = W + 2ft
Perimeter of rectangle, P = 2L + 2W
Given; P = 36ft
36ft = 2W + 2(W + 2ft)
36ft = 2W + 2W + 4ft
32ft = 4W
8ft = W
L = W + 2ft
L = 8ft + 2ft
L = 10ft
