Find the Area of the Shaded Region $x ^ { 2 } + 4 ; 68$

Find the area of the shaded region. Write the answer as a polynomial in descending powers of x.
-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 3 yards and the adjacent side (the right side of the figure) is increased by 1
Yard. 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 8 yards on a side.

A) $x ^ { 2 } + 4 ; 68$ square yards
B) $x ^ { 2 } + 4 ; 99$ square yards
C) $x ^ { 2 } + 4 x + 3 ; 68$ square yards
D) $x ^ { 2 } + 4 x + 3 ; 99$ square yards
