Question

Find the area.
a = [?]cm²
4.5 cm, 12 cm and 4.3 cm
Shape: Parallelograms

Answer 1

To find the area of a parallelogram, you can use the formula:

\[ \text{Area} = \text{base} \times \text{height} \]

From the dimensions you provided (4.5 cm, 12 cm, and 4.3 cm), we can identify the base and the height.

1. **Identify Base and Height**:
- Let's take \( 12 \, \text{cm} \) as the base, but we do not know the height from the given dimensions. However, typically in a parallelogram, the height can often be represented along with one of the non-base lengths.

To calculate the area, we need the height corresponding to the base.

**Given there is no specific height provided**, let's assume one of these dimensions is the height. The most reasonable assumption is that \( 4.5 \, \text{cm} \) or \( 4.3 \, \text{cm} \) might represent the height if they are meant to be perpendicular.

- If we assume \( 4.3 \, \text{cm} \) is the height, the area will be:

\[
\text{Area} = 12 \, \text{cm} \times 4.3 \, \text{cm} = 51.6 \, \text{cm}^2
\]

- If we assume \( 4.5 \, \text{cm} \) is the height, the area will be:

\[
\text{Area} = 12 \, \text{cm} \times 4.5 \, \text{cm} = 54 \, \text{cm}^2
\]

### Summary:
- **Assuming height is 4.3 cm**: Area = \( 51.6 \, \text{cm}^2 \)
- **Assuming height is 4.5 cm**: Area = \( 54 \, \text{cm}^2 \)

### Final Result:
We cannot definitively state the area without knowing which height corresponds to the base. Please confirm the height for accurate calculations. Otherwise, based on assumptions:

- \(\text{Area} = 51.6 \, \text{cm}^2 \) or \(54 \, \text{cm}^2 \).
