If `L = 2.01 m +- 0.01 m`, what is 3L?

Explanation

To solve the problem, we need to calculate \(3L\) given that \(L = 2.01 \, \text{m} \pm 0.01 \, \text{m}\).

### Step-by-Step Solution:

1. **Identify the given values**:
- The measured length \(L = 2.01 \, \text{m}\)
- The uncertainty in the measurement (error) is \(\Delta L = 0.01 \, \text{m}\).
