To calculate the area of a parallelogram, we use the formula:

$\text{Area} = \text{Base} \times \text{Height}$

However, in your question, only the base is provided (3 cm). We also need the height to find the area. Could you provide the height of the parallelogram?

Let me know if you need help with that or if you'd like further explanation.

Follow-up questions:

1. Do you know the height of the parallelogram?
2. Are there other dimensions or angles provided in the problem?
3. Would you like to explore how to calculate the area using trigonometry if the angles are given?
4. Is the parallelogram part of a larger figure or context in your problem?
5. Would you like a detailed explanation of how the height is determined in different types of parallelograms?

Tip: The height in a parallelogram is always perpendicular to the base, not along the slant.
