Answer:
119 mi^2
Explanation:
Let's split this up into three shapes: Three rectangles stacked on top of each other.
The first rectangle is 8 by 4, which is 32 mi^2.
The second rectangle's width is 8 - 2 - 2. This is 4. 4 times 6 is 24 mi^2.
The third rectangle is 7 by 3 + 4 (we know it's 4 because of previous step) + 2. This means the third rectangle is 7 by 9, which is 63 mi^2.
When you add 32, 24, and 63, you get 119 mi^2.
