Answer:

13.5ft^2

Step-by-step explanation:

Since the triangles that make the parallelogram are congruent, their areas are equal. So, the area of each triangle is 1/2 (half) the area of the parallelogram.

27/2 = 13.5

Answer:
13.5 ft².

Step-by-step 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 =

(1)/(2)bh (formula for area of a parallelogram. A=bh).
