Question 63260
Let the width of the rectangle be x in.
So length = (2x + 2) in

Then perimeter = 2*(l + w)
               = 2*(2x + 2 + x)
               = 2*(3x + 2)
               = 6x + 4

Given perimeter = 34

==> 6x + 4 = 34
==> 6x + 4 - 4 = 34 - 4
==> 6x = 30
==> 6X/6 = 30/6
==> X = 5

So the width of the rectangle = 5 in
length of the rectangle = 2x + 2
                        = 10 + 2
                        = 12 in


Good Luck!!!
