Answer:
107 square millimeters
Step-by-step explanation:
You can make this problem easier by splitting this into pieces you already know how to solve. So, you can draw a line down the middle to get 2 rectangles whose formula are Length X Width. Now, use the side lengths 5x7=35 and 8x9=72.
Add the 2 area of rectangles together to get 107 which is your total area.
So you reversed the subtraction a bit; the equation you're gonna be solving is 
.
First step ya gonna do is to reverse the + and - symbols in the trinomial thats in the parentheses so your equation looks like
Now just combine like terms and your answer should be
