    Resistivity does not depends on length and area but resistance depends on it so the new resistance will be four times of previous resistance. Resistance=resistivity×length/area.

    Resistance will remain same And resistivity also b/c resistivity does not depend on length and area of conducter it depends on temp and nature of material

    2Thank You
