Hmm confusing don't understand

7.1 is in between -8 and -7 because -7. 1 is equal to -7. 10 and that number is 10 numbers away from the number 7. ur welcome!

Use pythagorean’s theorem and find the missing side lengths of the two smaller triangles and add them together
13^2 - 12^2 = 5
15^2 - 12^2 = 9
5+9 = 14
14 is the length of each side of the square
14^2 + 14^2 = 19.8
19.8 is the diagonal length of the inside if the square
