If QSR: YXZ describes two triangles, which other statement is also true? QRS - XYZ
QRS = YZX
QRS = ZXY
QRS XZY

The answer is 15×7=105therefore, 105×5=525 miles

It’s either a or c as 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
