Compose a rectangle to find the area of a trapezoid shaped tabletop in square inches. What is the area of the tabletop? The top base of the trapezoid is 36 in. The bottom base is 48 in. The two sides of the trapezoid are 21 in.

(Choose ONE answer choice)

A. 864 square inches

B. 882 square inches

C. 756 square inches

D. 648 square inches

To find the area of the trapezoid shaped tabletop, we can use the formula for the area of a trapezoid:

Area = (1/2) * (top base + bottom base) * height

Plugging in the values given:

Area = (1/2) * (36 + 48) * 21
Area = (1/2) * 84 * 21
Area = 42 * 21
Area = 882 square inches

Therefore, the area of the tabletop is 882 square inches.

So, the correct answer is:

B. 882 square inches
