Answer:

it decreases as resistivity = area/length

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.
