what is the area of the rhombus?
**Finding the Area of a Rhombus**

In this lesson, we will learn how to find the area of a rhombus using its diagonals.

### Given Information
- One of the diagonals is 16 meters long.
- The other diagonal is 12 meters long.

### Diagram Explanation
The provided diagram shows a rhombus with its diagonals intersecting at right angles. The diagonals are drawn as two perpendicular lines dividing the rhombus into four right-angled triangles.

- The length of the vertical diagonal is marked as 16 meters.
- The length of the horizontal diagonal is marked as 12 meters.

### Formula for the Area of a Rhombus
The area \( A \) of a rhombus can be calculated using the lengths of its diagonals \( d_1 \) and \( d_2 \) with the formula:
\[ \text{Area} = \frac{1}{2} \times d_1 \times d_2 \]

### Calculation
Substitute the given lengths of the diagonals into the formula:
\[ \text{Area} = \frac{1}{2} \times 16 \, \text{m} \times 12 \, \text{m} \]

### Final Area
\[ \text{Area} = 96 \, \text{m}^2 \]

### Conclusion
The area of the rhombus is \( 96 \, \text{m}^2 \).

Feel free to use this formula to calculate the area of any rhombus if the lengths of its diagonals are known.
