area get doubled and length get reduced to half
R1/R2=(L1/L2)×(a2/a1)
R1/R2={L1/(L1/2)}×{(2*a1)/a1}
6/R2={2}×{2}
R2=6/4
R1/R2=(L1/L2)×(a2/a1)
R1/R2={L1/(L1/2)}×{(2*a1)/a1}
6/R2={2}×{2}
R2=6/4

i removed the pic
ur ans is still worng .. the correct ans is 6/4 ohms
buddy 6/4 means 3/2
got it
????
yes !
but give the steps .. friend
