plz add brainlist to my answer to know full answer
I will give some answer
Resistivity is a property of materials, so it has no sense to ask for the resistivity of a wire unless it is implied that you are referring to the resistivity of what is the wire made of.
Resistance is a property of a wire or others objects, so it would be different depending of the material and the dimensions.

No the resistance will not be same!!
The resistance of a material can be calculated by
R=(pL/A)
Resistance = (resistivity x length) / area
[*Length is in meter
Resistance is in ohms
cross-sectional area is in meter^2 [ square meter]
Resistivity is in ohms-meter.
