Answer:

A cylindrical conductor of length L and uniform area of cross section A

◇ 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. therefore, the area of cross-section is 2A.
