Explanation:
The Resistivity of the wire will not change with the change in length. Resistivity is a property of the wire, it doesn't depend upon it's length or cross-sectional area. However, If you are asking about Resistance, it will increase to 4 times it's initial value

Explanation:
The resistivity of wire or any conductor does not depend upon the length, shape or size of conductor so if the length is doubled its resistivity will same.
The resistivity of conductor is constant at given temperature.
