To find the area of a trapezoid, you use the formula:
\[ \text{Area} = \frac{1}{2} \times (b_1 + b_2) \times h \]
Where \( b_1 \) and \( b_2 \) are the lengths of the two parallel sides (bases) and \( h \) is the height.
From the values given:
- \( b_1 = 4 \)
- \( b_2 = 15 \)
- \( h = 3 \)
Now plug these values into the formula:
\[ \text{Area} = \frac{1}{2} \times (4 + 15) \times 3 \]
\[ \text{Area} = \frac{1}{2} \times 19 \times 3 \]
\[ \text{Area} = \frac{1}{2} \times 57 \]
\[ \text{Area} = 28.5 \]
It looks like there is no option that matches this result. Therefore, please double-check the values provided or ensure the trapezoid's dimensions given are correct.
