PLEASE HURRYHHHYH.

so how do I do this it’s about translation and it’s due

Ibelieve the answer is b

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

17.40$u turn the 9.8 to a 1010÷ 1.74 is 17.4 which is 17.40(u add the 0)
