it's inversely proportional
P.S. :- the resistance of a wire is proportional to its length, and inversely proportional to its cross-sectional area. The constant of proportionality is called the resistivity of the material making up the wire. And resistivity is inversely proportional to resistance,hence length of wire is inversely proportional to resistivity ☺☺
