Which statement best explains why the sum of the areas of the
two white squares in Figure 2 is
the same as the area of the whit
square in Figure 1?

Bwould be the answer

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
