R-reaistance,ฯ-resistivityVolume=const.A*L=A`*L/2A`=2AInitial resistance,R=ฯL/AFinal resistance,R`=ฯL/4AR`=R/4.Hope u understood.

Rsistance of a wire is directly proportional to the legth of wire.
If length is doubled by adding same wire then new reistance will be doubled.
and if length is doubled by streching then resistance will be four times of initial.
