Answer:448 Square feet
Explanation: I broke down the image into two rectangles I made the one on top 22 x 13 (I got 13 Because I took 31 and subtracted the bottom portion) my second rectangle was 18 x 9 to find the area of a rectangle you multiply the numbers
22x13=286 18x9=162
Then I added The answers together to get the total area
286+169=448
so total area=448
