Answer 3

For figure one you have to find the missing side. You would have to use the Pythagorean theorem which is a^2 + b^2 = c^2. You should get 6. After that you have to use the same steps to find he missing part for figure 2. You should get 9.16. After you round you have to subtract the two from each other getting 3 or 3.2.
