To find the area of the triangle in the image, we can use the following formula for the area of a triangle when two sides and the included angle are known:

\[
\text{Area} = \frac{1}{2} \times a \times b \times \sin(C)
\]

Where:
- \( a = 3 \) (one side of the triangle),
- \( b = 5 \) (another side of the triangle),
- \( C = 30^\circ \) (the angle between these two sides).

Now, we can calculate the area by plugging these values into the formula. The sine of \( 30^\circ \) is \( \frac{1}{2} \).

\[
\text{Area} = \frac{1}{2} \times 3 \times 5 \times \sin(30^\circ)
\]
\[
\text{Area} = \frac{1}{2} \times 3 \times 5 \times \frac{1}{2}
\]
\[
\text{Area} = \frac{1}{2} \times 7.5 = 3.75
\]

So, the area of the triangle is **3.75**. The correct answer is the second option: **3.75**.
