If all the sides of a right triangle increase in length by 8%, then by what percentage does the area of the triangle increase?	Pick one.
A) 8%  B) 16.64%  C) 24.32%  D) 32.84%  E) 36.16%
Let B be the base and H be the height of the original triangle.   The original area is (1/2)BH.   The area of the expanded triangle is (1/2)(1.0816.64%)(1.08H) = (1.08)(1.08)(1/2)16.64%H = 1.1664(1/2)16.64%H   The answer is 16.64%.
