Answer:
Resistivity doesn't actually depend on length and area rather it depends on type of material. It is constant which is used to determine the resistance of a material.
Resistivity, electrical resistance of a conductor of unit cross-sectional area and unit length. A characteristic property of each material, resistivity is useful in comparing various materials on the basis of their ability to conduct electric currents.
When current flows through a component, the resistance depends on the geometry (length and cross-sectional area) of the component and a property of the material which is known as its resistivity. Resistivity itself is dependent upon temperature
