since resistance is directly proportional to Length... the resistance will also double..
Here is the expression
R= Rho×Length/Area
R is the resistance..
Here is the expression
R= Rho×Length/Area
R is the resistance..

When length is doubled.area becomes half.so that new resistance will be
4 of old resistance
