Answer:
You have to break it into two rectangles.
Step-by-step explanation:
Once you have it in two rectangles, I found the width of the smaller rectangle because I know the whole side is 16. I know the larger rectangle has a width of 13. I subtracted to find that extra little bit of space is 3. The formula for a rectangle is length x width. Now you just need to find the area of each rectangle and add them together.
