Answer:

31 in sq

Step-by-step explanation:

The interior shape is inside the exterior shape

first get the area of the big shape

9 times 15 = 135 in sq  

now get the area of the interior shape:  

8 times 13 = 104 in sq

now subtract interior shape from exterior

135 - 104 = 31 in sq

that's the shaded part

Answer:

31 ins^2.

Step-by-step explanation:

The area of the shaded region = area of the exterior rectangle - area of the inner rectangle

= (9 * 15) - (8 * 13)

=  135  - 104

= 31 ins^2.
