#### Answer

$499\ in^2$

#### Work Step by Step

Find the area of each of the 3 rectangles that make up the figure, then sum to find the area of the figure.
The top rectangle has sides that are 11 in an 9 in.
$11\times9=99$
The middle rectangle has sides that are 22 in (11+11) and 8 in.
$22\times8=176$
Find the height of the bottom rectangle by subtracting the heights of the two upper rectangles from the total height.
$24-(9+8)=24-17=7$
The bottom rectangle has sides that are and 32 in and 7 in.
$32\times7=224$
$99+176+224=499$
