Answer:
87.5 square inches
Step-by-step explanation:
The first thing i did was get all of that middle space out of the way by doing a 5x13 rectangle. I got those dimensions by adding the 4, 6, and 3 that comprise the height and multiplying that by the 5 on top.
I then added the 2x3 rectangle sticking out on the far bottom left.
I then added the 2x6 rectangle on the top left
Finally, I got the triangle on the right by subtracting 10 (the given lengths on the side of the triangle) from 13, the height of the shape. This, multiplied by the 3in side given, is a 3x3 triangle.
Just add the whole thing together!
