What is dielectric?

A substance has a dielectric constant 2.0 and its dielectric strength is 20 xx 10^(6) V/m . It is taken as a dielectric material in a parallel plate capacitor. The minimum area of its each plate such that its capacitance becomes 8.85xx10^(-2) muF and it can withstand a potential difference of 2000 V is ......
