Answer: 4 times of the original length

Explanation: Let's say the length was L and resistivity X then if the length is doubled its

new resistivity will be 4X

as Resistivity is directly proportional to length squared

Explanation:

As a wire gets longer its resistance increases , and as it gets thinner its resistances also increases because its cross sectional area decreases . doubling the length will double the resistance.
