Answer:
base = 2
height = 4
area = 8
Explanation:
If you let the left or right sides be the base, then the height is the perpendicular distance between. This is easier than using the top or bottom for the base because you don't have to calculate length. You can just count squares on the grid.
Area of a parallelogram is:
Area = b•h
= 2•4
= 8
