How can we reduce resistance of any resistor

Resistance of the resistor is givne by:R = ρLAwhere L is the length of the resistorA is te area of the cross-section of the resistor.if we decrease the length of the resistor or increase the area of the resistor , resistance of the resistor can be decreased.
