Detailed Solution

It is true that the length and area of the cross-section are some factors on which the resistance of a conductor depends.
It is known that for a uniform cross-sectional wire, the resistance depends on the length l, resistivity of the material and the area of the cross-section A of the conductor. It also depends on the temperature of the conductor. Mathematically, it can be written as

R = \frac{ρl}{A}
