The base AB is a horizontal line and its length is 7 - 2 = 5 units. The height is vertical line and its length is 2 - (-3) = 5. Hence, the area of the parallelogram is 5*5 = 25 square units.
Lines AB and CD are horizontal, are parallel, and measure 5 units each. Either one can be the base of the parallelogram
The height, or perpendicular segment from D to base AB is 5 (2 - - 3) units
Hence, bh, or
