Answer:

Explanation:

A - Area of a cross-section of the conductor.

From this relation, we observe that the length is directly proportional to the resistance and the area of cross-section is inversely proportional to the resistance.

In this case, the length of the conductor is doubled (2L) and so the resistance will be 2R. For the resistance to remain the same as R, the area of cross-section is also doubled as 2A.

Hence, the area of cross-section is 2A.
