R is directly proportional on conductor's length..
If L increases then R will also increase and if L decreases then R also decreases..
______________&___________________
R is inversely proportional to its A (area of cross section)
If A increase then R decreases and if A decrease then R increases...
so, this is how resistance of a conductor depends on its length and cross section area..
Hope it helps u!!☺☺☺☺☺☺☺☺☺☺☺

:-
1) :- The resistance of a conductor is directly proportional to the length. If the length increases, resistance increases and vice-versa.
2):- The resistance of a conductor in shape of wire is indirectly proportional to the area of Cross section. A thick wire has less resistance as its area of cross section is more.
________________________________
Resistance = ρ l/A
Where ρ is a constant for given temperature and is known as resistance. 'l' is the length and 'A' is the area of cross section.
_______________________________
Resistance also depends upon the and the
For example :- Copper has less resistance than manganese.
