Pat knows that one leg of a certain right triangle is 300 cm and the hypotenuse is 400 cm.

Pat notes that 300= 3*100 and 400= 4*100, and then uses the {3,4,5} Pythagorean

triple to determine that the other leg must be 5*100=500 cm. Explain why Pat’s method

doesn’t work and determine the correct length of the other leg of the triangle.
