1. An illustration shows a parallelogram with the left side labeled upper C and the right side labeled upper D. A dotted line, labeled upper B, runs from the top left vertex to the bottom right vertex. The base is extended to the right by a second dotted line. A dashed line, labeled upper A, runs from the top left vertex to the base, meeting the dotted base line. The three dotted lines form a triangle. Which dimension can be used in an equation that models finding the area of the parallelogram?
a)B.
b)A.
c)C.
d)D.
a) B.
The dimension B represents the height of the parallelogram, which is used to calculate the area of the parallelogram (area = base x height).
