Find area of figure. Round to the nearest hundredth if necessary.
-Of a trapezoid with short base of $21 \mathrm{yd}$, long base of $30 \mathrm{yd}$, and height of $11 \mathrm{yd}$
A) $315 \mathrm{yd}^{2}$
B) $280.5 \mathrm{yd}^{2}$
C) $165 \mathrm{yd}^{2}$
D) $561 \mathrm{yd}^{2}$

Question

Quizplus · Accepted Answer

The area of a trapezoid is given by the formula $\frac{1}{2}(b_1 + b_2)h$, where $b_1$ and $b_2$ are the lengths of the two bases, and $h$ is the height. Substituting the given values, we get $\frac{1}{2}(21 + 30) \times 11 = \frac{1}{2}(51) \times 11 = 280.5 \mathrm{yd}^{2}$.
