A rancher uses 240 meters of fencing to build two adjacent rectangular corrals on a flat piece of land along the side of a barn, as shown in the figure. The width of each corral is x meters, the two corrals share one common side, and no fencing is required along the side of the barn. Disregarding the thickness of the fence, what is the total area, in square meters, of the two corrals in terms of $$x$$?
