resistance depends on length & area of crossed section while resistivity depends on nature of material used & also on temperature .

when length is doubled resistance also doubled as they are directly proportional to each other.
Ya
But when it comes to cross section area the resistance is indirectly proportional to the cross section area of the wire That is R α 1/A

The resistance is directly proportional to the length of wire therefore
therefore if length is doubled that is 2l then resistance will also be doubled i.e. 2r. when again the wire is doubled that is 4l then consequently the resistance will also be doubled that is 4r.
I hope that it would have been clear to you buddy.
