Solution

The formula for the area of a trapezoid is A = 0.5 * (base1 + base2) * height. Given that the bases are 10.5 units and 16 units, and the height is half of the longer base (which is 16 units), the height is 8 units. Therefore, the equation to find the area of the trapezoid is A = 0.5 * (10.5 + 16) * 8. So, the correct answer is C: A = 0.5 * 8 * (10.5 + 16).
