Use fundamental relationships. length*width is area for a rectangle. Perimeter of a rectangle is 2 times the sum of length and width.
In symbols, or variables, if L is length and W is width, then:
2L+2W=perimeter, and L*W= area.
You are looking for area for your described rectangle. Use perimeter to find your unknown x, and then use this in your calculation for area, L*W.
