The hypotenuse is always the side with the greatest length. As the question asks for the largest possible length we have to calculate the hypotenuse.
Pythagoras theorem:
A^2 + B^2 = C^2
a = 15 b = 2
15^2 + 2^2 = 229
Square root 229 to get side length which is equal to 15.13~
Since it asks for largest possible WHOLE NUMBER side length round down to 15
