Q5 (7 points) In the right triangle below, assume that its base a is changing at a rate of 1 cm/s, and that its perimeter P is changing at a rate of 2 cm/s. How fast is the height h of the right triangle changing when the base :1 becomes 4 cm and the height h becomes 3 cm? Note that the perimeter P is given by P=\\/a2+h2+a+h. \f
