Answer:
240.5 square millimeters
Explanation:
I did this by taking apart the trapezoid and making a triangle and rectangle. To find the side of my triangle, I subtracted 15 from 22 to get 7. Then I multiplied 13 by 7 and divided that by 2 to get 45.5. Then for the rectangle, I multiplied 13 by 15 to get 195. Then I added those two values to get 240.5.
