If you take a paper that is 20 inches long and fold it across a diagonal that is 25 inches long, what must the width be?

Use Pythagorean theorem

   the diagonal is the hypotenuse    one leg is 20       find the other leg (width)

         h^2 = l1 + l2 2

         252  = 202  +  w2       Solve for w
