Hi!
I've included an image showing the shape divided into 3 rectangles. We're going to find the area of each rectangle.
To find the area of a rectangle, multiply the length times the width.
The red rectangle:
8 · 9 = 72
The area of the red rectangle is 72in.
The orange rectangles:
The orange rectangles have the same area.
10 · 3 = 30
30 + 30 = 60
The area of both orange rectangles is 60in.
72 + 60 = 132
The answer is 132 square inches.
Hope this helps! :)
