Solve.The square garden in the figure measures x yards on each side. The garden is to be expanded so that one side (the top of the figure) is increased by 4 yards and the adjacent side (the right side of the figure) is increased by 2 yards. Write a polynomial in descending powers of x that expresses the area of the larger garden. Then use the polynomial to determine the area of the larger garden if the original garden measures 5 yards on a side.
