The problem provided involves calculating the upper bound for the area of a rectangle. Let's go through it step by step.

### Given:
- The length of the rectangle is \(25.0 \, \text{cm}\) (correct to the nearest cm).
- The width of the rectangle is \(9.6 \, \text{cm}\) (correct to the nearest 0.1 cm).

### Step 1: Determine the Upper Bound of the Length and Width

1. **Upper Bound for Length:**
   - The length is \(25.0 \, \text{cm}\), correct to the nearest cm.
   - The upper bound for the length is \(25.0 + 0.5 = 25.5 \, \text{cm}\).

2. **Upper Bound for Width:**
   - The width is \(9.6 \, \text{cm}\), correct to the nearest 0.1 cm.
   - The upper bound for the width is \(9.6 + 0.05 = 9.65 \, \text{cm}\).

### Step 2: Calculate the Upper Bound of the Area

- The area \( A \) of a rectangle is given by:
  \[
  A = \text{length} \times \text{width}
  \]

- The upper bound for the area:
  \[
  A_{\text{upper}} = 25.5 \times 9.65 = 246.075 \, \text{cm}^2
  \]

### Final Answer:
- The upper bound for the area of the rectangle is **246.075 cm²**.
- You should write down all the figures on your calculator display, which would be **246.075**.
