Find the area of a rhombus whose side is 6 cm and whose altitude is 4 cm. If one of its diagonals is 8 cm long, find the length of the other diagonal.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Calculate the Area of the Rhombus
The area \( A \) of a rhombus can be calculated using the formula:
\[ A = \text{base} \times \text{height} \]
In this case, the base is the length of a side of the rhombus, which is 6 cm, and the height (altitude) is 4 cm.
