Let x represent the width, then x + 3 represents the length, in other words the two legs of the right triangle formed by the diagonal. So: Solve the quadratic using the quadratic formula. Discard the negative root because we are looking for a positive measure of length. The positive root will be the width. Add 3 to get the length. Remember to round to 2 places. John
