What work have you done so far on this problem? I and I'm sure others are more than willing to help, but we want to see some of your work first.

Start with the DEFINITION of perimeter, then go ahead and do the algebra. Since this house is basically a rectangle, opposite sides must have the same length. That will give you an equation to solve for x.
