A card is in the shape of a rhombus. If each side of the card is 16 cm, find its perimeter.

Answer

To find the perimeter of a rhombus when each side is given, follow these steps:

### Step-by-Step Solution:

1. **Understand the Shape**: A rhombus is a type of quadrilateral where all four sides are of equal length.

2. **Identify the Length of One Side**: According to the question, each side of the rhombus is 16 cm.

3. **Use the Perimeter Formula**: The formula for the perimeter (P) of a rhombus is:
\[ P = 4 \times \text{side length} \]

4. **Substitute the Side Length**: Substitute the given side length into the formula:
\[ P = 4 \times 16 \text{ cm} \]

5. **Calculate the Perimeter**: Now, perform the multiplication:
\[ P = 64 \text{ cm} \]

6. **State the Final Answer**: Therefore, the perimeter of the rhombus is 64 cm.
