The image shows a trapezoid with the following dimensions:

- The top side (DC) = 7 cm
- The height (perpendicular distance between AB and DC) = 8 cm
- The bottom side (AB) = 19 cm

To find the area of a trapezoid, the formula is:

\[
\text{Area} = \frac{1}{2} \times ( \text{Base}_1 + \text{Base}_2 ) \times \text{Height}
\]

Where:
- \( \text{Base}_1 = 19 \, \text{cm} \) (AB)
- \( \text{Base}_2 = 7 \, \text{cm} \) (DC)
- Height = 8 cm

Let me calculate the area for you.The area of the trapezoid is \( 104 \, \text{cm}^2 \). Therefore, the correct answer is:

**B. 104 cm²**

Do you want more details or have any questions about the calculation?
