resistance is directly proportional to length of the wire
hence
(3.75/85)=(x/510)
x= (3.75/85)*510
x= 22.5 ohms
hence
(3.75/85)=(x/510)
x= (3.75/85)*510
x= 22.5 ohms

Answer:
length1 =85 cm and L2 is 510 cm
resistance 1 is 3.75 ohm and R2 is ?
since r1 is proportional to L1
similarly for R2 is proportional to L2
therefore r1/R2 =L1/ L2
3.75/85510/R2
R2=510x85/3.75
therefore R2=22.5ohm
