What is the total area of a quilt made up of parallelogram-shaped pieces, if each piece has a base measure of 9 inches and a height of 12 inches, and 20 pieces are used in the quilt?

A) 180 in
B) 360 in
C) 720 in
D) 1440 in

To find the total area of the quilt, we need to find the area of each parallelogram-shaped piece and then multiply it by the number of pieces used.

The area of a parallelogram can be found by multiplying the base measure by the height. In this case, the base measure is 9 inches and the height is 12 inches.

Area of one parallelogram = base measure * height = 9 inches * 12 inches = 108 square inches.

Since there are 20 pieces used in the quilt, we multiply the area of one parallelogram by 20.

Total area of the quilt = area of one parallelogram * number of pieces = 108 square inches * 20 = 2160 square inches.

None of the given answer choices match the calculated result of 2160 square inches.

To find the total area of the quilt, you need to multiply the base measure and height of each parallelogram-shaped piece, and then multiply that by the number of pieces used.

In this case, the base measure of each piece is 9 inches and the height is 12 inches. To find the area of each piece, you multiply the base measure and height:

9 inches * 12 inches = 108 square inches

Now, you have the area of one piece, which is 108 square inches. To find the total area of the quilt, you multiply the area of one piece by the number of pieces used:

108 square inches * 20 pieces = 2160 square inches

Therefore, the total area of the quilt made up of parallelogram-shaped pieces is 2160 square inches.
