Hey friend ur answer is:
Electrical resistivity (also known as resistivity, specific electrical resistance, or volume resistivity) is a fundamental property that quantifies how strongly a given material opposes the flow of electric current. A low resistivity indicates a material that readily allows the flow of electric current. Resistivity is commonly represented by the Greek letter ρ (rho). The SI unit of electrical resistivity is the ohm-metre (Ω⋅m).[1][2][3] As an example, if a 1 m × 1 m × 1 m solid cube of material has sheet contacts on two opposite faces, and the resistance between these contacts is 1 Ω, then the resistivity of the material is 1 Ω⋅m.
A low resistivity indicates a material that readily allows the flow of electric current.Resistivity is commonly represented by the Greek letter ρ (rho). The SI unit of electrical resistivity is the ohm-metre (Ω⋅m).

No need to talk any further
which version do u have
Shut up

Electrical resistivity or also called as specific resistance is a constant which coincides with L/A. It is called as rho. It's SI unit is ohm/metre
Rho= RA/L ( I.e. resistance * area/ length)
Rho= RA/L ( I.e. resistance * area/ length)
