If all the sides of a right triangle increase in length by 20%, then by what percentage does the area of the triangle increase?  Choose the correct choice from the following options.
A) 36%
B) 44%
C) 50%
D) 64%
E) 80%
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)(1.244%)(1.2H) = (1.2)(1.2)(1/2)44%H = 1.44(1/2)44%H   The answer is 44%.
