in the next problems, find the area of each figure. Use 3.14 as an approximation for $\pi$ as needed. Round answers to the nearest tenth.
-A trapezoid with bases $12.2 \mathrm{~cm}$ and $9.4 \mathrm{~cm}$ and height $3.6 \mathrm{~cm}$.
A) $25.2 \mathrm{~cm}^{2}$
B) $114.7 \mathrm{~cm}^{2}$
C) $38.9 \mathrm{~cm}^{2}$
D) $77.8 \mathrm{~cm}^{2}$

Question

Quizplus · Accepted Answer

The area of a trapezoid is calculated using the formula: $\frac{1}{2} \times (\text{Base}_1 + \text{Base}_2) \times \text{Height}$. Substituting the given values: $\frac{1}{2} \times (12.2 + 9.4) \times 3.6 = 38.88$, which rounds to $38.9 \mathrm{~cm}^{2}$.
