Question

The area of a trapezoid is found using the formula A = h(b1 + b2), where A is the area, h is the height, and b1 and b2 are the lengths of the bases. What is the area of the trapezoid below?

h = 4
A. A = 4x + 2
B. A = 4x + 8
C. A = 2x² + 4x - 21
D. A = 2x² + 8x - 42

Answer 1

The area of a trapezoid is calculated with the formula A = h(b1 + b2)/2. The division by 2 is essential and was incorrectly omitted in the provided options.

Step-by-step explanation:

The area of a trapezoid is found using the formula A = h(b1 + b2)/2, where A is the area, h is the height, and b1 and b2 are the lengths of the bases. However, the formula given in the student's question seems to be missing the division by 2. With the provided formula, none of the options (A to D) appears to be correct because all are missing the division by 2. With the corrected formula, you would calculate the area by inserting the values for the height and the bases, then divide by 2 to obtain the final answer.
