Answer:
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

Resistivity is directly proportional to the length,
so if length will increase resistivity will also increase.
