You can put this solution on YOUR website!
L = length
W = width
P = perimeter = 34
The length of the rectangle is 2 inches more than twice its width:
L = 2W + 2..............(i)
The perimeter is the sum of all side lengths:
P = 2W +2L..............(ii)
Subtitute equation (i) into (ii) for L:
P = 2W +2(2W + 2)
P = 2W + 4W + 4
P = 6W + 4
P = 34
6W + 4 = 34
6W = 30
W = 5 in.
Subtitute W=5 into equation (i) for W:
L = 2(5) + 2
L = 12 in.
I hope this helps
