The perimeter of the front face of a prism is 88 feet. The side lengths of the front face are 2x feet, (4x+8) feet, 2x feet, and (4x+8) feet. What is the value of x?

 2x + 4x + 8 +2x +4x + 8 = 88

                        12x +16 = 88   | -16

                               12x = 72   | :12

                                  x = 6
