Calculating capacitor leakage resistance???

[Puppydog]

Can anyone help me answer this question?

The question at first sight appears to be badly specified.

However:

We know the capacitance and the permittivity of the dielectric, so it should be easy to calculate the area of the plates.

The resistivity of sheet material is usually specified in Ohm/Square.
Square what? you may ask.
Just Ohm/Square, think about it.

What we dont know is the thickness of the dielectric, but maybe we can make a few assumptions and it doesn't matter, think about it.

Cheers Jim!

OK..... I get Ohms per square metre. I guess some reverse algebra equations in my course notes should get me to the plate size......
