The right triangle has two sides, usually one shorter than the other, and the hypotenuse. The hypotenuse is the longest side. Let's call one side a and the other b, and the hypotenuse h
Pythagoras:
h=+sqrt%28a%5E2%2Bb%5E2%29
h=+sqrt%2812%5E2%2B9%5E2%29
h=+sqrt%28144%2B91%29
h=+sqrt%28235%29
h=+15.33 is the length of the hypotenuse, which you problem calls "the longest side".
