How does the resistance of a conductor depend on its length and cross sectional area?

Two wires are made of the same material and have the same volume. The first wire cross sectional area A and the second wire has cross sectional area 3A.

Equal increase in length occurred in two wires, one is of steel of cross sectional area 3.0 xx10^-5 m^2 and another one is of copper of cross sectional area 4.0xx10^-5m^2 , by applying equal load on them. If Young's modulus of steel and copper are 2.0xx10^11 Nm^-2 and 1.0xx10^11Nm^-2 respectively, then the ratio of their initial lengths will be
