A metal wire of resistance `6Omega` is stretched so that its length is increased to twice its original length. Calculate its new resistance.

Explanation

To solve the problem of finding the new resistance of a metal wire after it has been stretched to twice its original length, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Initial Resistance Formula**:
The resistance \( R \) of a wire is given by the formula:
\[
R = \frac{\rho L}{A}
