## Rectangle Problem

A rectangle is formed by bending a wire that is **32 centimeters** long. The length of the rectangle is **12 centimeters**.

**Question:**
What is the width, in centimeters, of the rectangle?

### Given Data:
- Length of the wire: **32 cm**
- Length of the rectangle: **12 cm**

### Solution:

1. Recall the formula for the perimeter (P) of a rectangle:
\[ P = 2 \times ( \text{length} + \text{width} ) \]

2. Substitute the given values into the perimeter formula:
\[ 32 = 2 \times ( 12 + \text{width} ) \]

3. Simplify the equation:
\[ 32 = 24 + 2 \times \text{width} \]

4. Subtract 24 from both sides:
\[ 8 = 2 \times \text{width} \]

5. Divide both sides by 2:
\[ \text{width} = 4 \]

Thus, the width of the rectangle is **4 centimeters**.

### Diagram Explanation:
There is a visual representation of a rectangle with clearly marked dimensions. The length is indicated as **12 cm** and the width is represented as a blank space meant to be filled with the correct width value, which we've calculated as **4 cm**.
