Answer:
The area of shaded region is 208 sq.feet
Explanation:
Refer the attached figure
ABCD is rectangle
Opposite sides of rectangle are equal so
AB = CD = 16 feet
AD = BC= 17 feet
Area of rectangle =

Now In triangle PCD
CD = 16 feet
PC = BC-BP = 17-9 = 8 feet
Since all angles of rectangle is 90°
So,PCD is a right angles triangle
So, Area of triangle =

Area of shaded region = Area of rectangle - Area of triangle =

Hence The area of shaded region is 208 sq.feet
