What is the area

Let the area of the plates of capacitor be A.

Capacitance of a parallel capacitor (C) = 2 F

Distance between the two plates (d) = 0.5cm = 0.005m

Capacitance of a parallel plate capacitor is given by the relation,

Where,

= Absolute Permittivity of free space = 8.8510^-12 C²N^-1m^-2

= 0.001129910¹²m² ~ 1130km²

As the area of the plates required becomes too large so the capacitance is taken in the range of μF .
