Question: What is the area of a trapezoid with bases of lengths 5 and 7 units and a height of 4 units?

Options:

1. 24
2. 28
3. 20
4. 32

Correct Answer: 24

Solution:

The area A of a trapezoid is given by the formula: A = 0.5 * (base1 + base2) * height. Here, A = 0.5 * (5 + 7) * 4 = 0.5 * 12 * 4 = 24.
