The area of a trapezoid is calculated using the formula: A = (1/2)h(b1 + b2), where h is the height of the trapezoid, b1 is the shorter base, and b2 is the longer base.
Plugging in the values given:
A = (1/2)(8)(20 + 30)
A = (1/2)(8)(50)
A = 4(50)
A = 200 ft^2
Therefore, the area of the trapezoid outlined in the image is 200 ft^2.
Correct response: 200 ft. squared
