Area of the shaded region is 41 square feet and area of the unshaded region if 87 square feet.
First I found the area of the big rectangle which was 128 ft^2 (16x8)
Then I turned the shaded area into a trapezoid by extending the bottom right corner of the region and I calculated its area which was 45 ft^2 ((6+3)x10)/2).
Then I calculated the area I added to the bottom right of the shaded region to turn it into a trapezoid which was 4 ft^2 (2x2)
After that, subtracted the unshaded area at the bottom right from the trapezoid area which gave me the area of the shaded area: 41 ft^2 (45 - 4)
Finally I subtracted the area of the shaded region from the area of the rectangle to find the area of the unshaded region which is 87 ft^2 (128 - 41)
