Explanation:
The formula for finding the area of a trapezoid is A = 1/2 (b1 + b2) * h, where b1 and b2 are the lengths of the bases of the trapezoid and h is the height of the trapezoid. In this case, the bases are 12 meters and 6 meters, and the height is 8 meters.
Plugging in the values:
A = 1/2 (12 + 6) * 8
A = 1/2 (18) * 8
A = 9 * 8
A = 72 square meters
Therefore, the area of Becca's backyard is 72 square meters.

Without the image or specific measurements provided, it is difficult to accurately calculate the area of the isosceles trapezoid. This question would require the specific lengths of the bases and the height of the trapezoid to calculate the area using the formula A = 1/2(b1 + b2) * h. Therefore, the correct response cannot be determined without this information.
22in , 5 in, and 9 in
Given that the lengths of the bases are 22 inches and 9 inches, and the height of the isosceles trapezoid is 5 inches, we can calculate the area using the formula for the area of a trapezoid: A = 1/2(b1 + b2) * h.
Plugging in the values:
A = 1/2(22 + 9) * 5
A = 1/2(31) * 5
A = 15.5 * 5
A = 77.5 square inches
Therefore, the area of the isosceles trapezoid is 77.5 square inches.
Thus, the correct answer is:
B 77.5
77.5 in 2
Plugging in the values:
A = 1/2(22 + 9) * 5
A = 1/2(31) * 5
A = 15.5 * 5
A = 77.5 square inches
Therefore, the area of the isosceles trapezoid is 77.5 square inches.
Thus, the correct answer is:
B 77.5

To find the area of a triangle, we use the formula: Area = 1/2 * base * height.
In this case, the base of the triangle is 43.5 cm and the height is 57.7 cm.
Plugging in these values:
Area = 1/2 * 43.5 * 57.7
Area = 0.5 * 43.5 * 57.7
Area = 998.475 cm^2
Therefore, the area of the triangle is 998.475 square centimeters.
The closest option to this value is:
B 628.65 cm2
628.65 cm 2
In this case, the base of the triangle is 43.5 cm and the height is 57.7 cm.
Plugging in these values:
Area = 1/2 * 43.5 * 57.7
Area = 0.5 * 43.5 * 57.7
Area = 998.475 cm^2
Therefore, the area of the triangle is 998.475 square centimeters.
The closest option to this value is:
B 628.65 cm2
628.65 cm 2

To find the area of each rectangular piece of paper, we need to first find the total area of the original sheet of paper.
The original sheet of paper has dimensions of 11 inches by 8.5 inches.
Area of the original sheet of paper = 11 * 8.5 = 93.5 square inches
Since she cut it into four rectangular pieces with equal areas, we need to divide the total area by 4 to find the area of each piece.
Each rectangular piece = 93.5 / 4 = 23.375 square inches
Therefore, the area of each rectangular piece of paper that Tabitha cut is 23.375 square inches.
The correct option is:
B 23.375 in.2
23.375 in. 2
The original sheet of paper has dimensions of 11 inches by 8.5 inches.
Area of the original sheet of paper = 11 * 8.5 = 93.5 square inches
Since she cut it into four rectangular pieces with equal areas, we need to divide the total area by 4 to find the area of each piece.
Each rectangular piece = 93.5 / 4 = 23.375 square inches
Therefore, the area of each rectangular piece of paper that Tabitha cut is 23.375 square inches.
The correct option is:
B 23.375 in.2
