As shown in the figure, M is a point on the side ad of the parallelogram. If the area of the parallelogram ABCD is four square centimeters, what is the area of the triangle MBC

The bottom and height of parallelogram ABCD are the same as that of triangle MBC, so the area of triangle MBC is equal to half of parallelogram ABCD, and the area of parallelogram ABCD is 4 square centimeters, so the area of triangle MBC is 2 square centimeters
