In the figure above, if the area of square region WXYZ is equal to the area of the triangular region RST, then RT =

The area of a square is s^2, where s = a side of the square. The area of a triangle is (½)bh, where b and h are the base and height of the triangle, respectively. We can let RT = b and create the following equation:

6 x 6 = (1/2) x b x 9

72 = 9b

8 = b

Answer: E
