a) in region X
8 in
b) in region Y
c) in region Z

The diagonal WY is formed by connecting W and Y. The coordinates of its midpoint are the average of coordinates of the endpoints. Below are the calculations.
                 abscissa : (0 + 6) / 2 = 3
                 ordinate:   (2 + 6) / 2 = 4
Thus, the midpoint is ate (3, 4).
