If the area of parallelogram abcd is 27 square feet, what is the area of triangle abc? a. 27 ft2 b. 54 ft2 c. 13.5 ft2 d. 13 ft

13.5 ft².

Explanation:
A parallelogram is bisected by its diagonal so the area is also bisected.
A bisected figure is exactly half of the measurement of the original figure.

Half of 27 square feet is 13.5 square feet.The formula for finding area of a triangle is:
A = bh (formula for area of a parallelogram. A=bh).
