Quizplus · Accepted Answer

The area of a trapezoid is given by the formula $ \frac{1}{2} \times (b_1 + b_2) \times h $, where $b_1$ and $b_2$ are the lengths of the bases, and $h$ is the height. Substituting the given values, $ \frac{1}{2} \times (18 + 16) \times 11 = \frac{1}{2} \times 34 \times 11 = 187 $ cm².
