There is one rod of length L. the resistivity of its material is given by `rho=alphax+beta`. Here x is the distance of `alpha` point on rod from one of its ends. Assume A as the area of cross section of rod. Find the electrical resistance of the rod.

Explanation

To find the electrical resistance of a rod with a non-constant resistivity, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Problem**:
The resistivity of the rod is given as \( \rho = \alpha x + \beta \), where \( x \) is the distance from one end of the rod. The rod has a length \( L \) and a cross-sectional area \( A \).

2. **Setting Up the Resistance Formula**:
