What is the area of this figure? ?

plzzz

189cm^2

Step-by-step explanation:

To find the area of the quadrilateral, you must find the area of each individual shape first. Doing this yields an area of 54 per triangle, or 108cm^2 for both. Next you must multiply the sides for the squares to get 81cm^2. Lastly, you just need to add them together to get a final answer of 189cm^2
