200 ft.2
200 ft. squared
300 ft.2
300 ft. squared
400 ft.2
400 ft. squared
240 ft.2
To find the area of the trapezoid, you can use the formula:
Area = (1/2) * (sum of bases) * height
In this case, the sum of the bases is 20 + 30 = 50 feet. The height is 8 feet.
Area = (1/2) * 50 * 8
Area = 0.5 * 50 * 8
Area = 25 * 8
Area = 200 ft^2
Therefore, the correct answer is 200 ft^2 or 200 ft. squared.
