Find the area of the parallelogram.
A parallelogram is shown with a horizontal base labeled 2.3 centimeters.From the base, a dashed line segment is drawn, ending at a point just below the upper right vertex of the parallelogram. A vertical dashed line segment is drawn from the endpoint to the upper right vertex. This segment is labeled 6.4 centimeters. A small square is placed along the two dashed lines with the point of intersection as the lower right vertex of the square.

The area of a triangle can be found using the formula A = (1/2)bh, where b is the base and h is the height.
For the first triangle with a base of 22 feet and a height of 7 feet, the area is A = (1/2)(22)(7) = 77 ft². Therefore, the answer is C. 77 ft².
For the second inverted triangle with a base of 20.3 centimeters and a height of 6.2 centimeters, the area is A = (1/2)(20.3)(6.2) = 62.93 cm². Therefore, the answer is B. 62.93 cm².
For the parallelogram with a base of 2.3 centimeters and a height of 6.4 centimeters, the area is A = (2.3)(6.4) = 14.72 cm². Therefore, the answer is C. 14.72 cm².
For the triangle with a base of 14 cm and a height of 5.5 cm, the area is A = (1/2)(14)(5.5) = 38.5 cm². Therefore, the answer is C. 38.5 cm².
For the parallelogram with a base of 5 cm and a height of 20 cm, the area is A = (5)(20) = 100 cm². Therefore, the answer is A. 100 cm².
