Give us some idea where the difficulty is and what you've tried. We'll give advice then. K?

Under root (X2X1) the whole square +(Y2Y1) the whole square.
Under root (1(7))whole square + (411)whole square.
Under root (1+7)whole square + (15)whole square.
Under root 8 square + 225
Under root 64 + 225
Under root 289
square root of17 is 289
SO ROOT OF 289 IS 17
ANSWER IS 17.
