The area is πab, assuming an ellipse with semi-major axis a and semi-minor axis b (where a≥b).

Since you wrote b≥a, and not b>a, If b=a, then a=b, so the formula still applies, but it's not an oval, it's a circle. Technically an elipse has to have the semi-major axis (a) longer than the semi-minor axis (b).

But there is a detailed explanation of your question here:

It's at least larger than an atom of hydrogen.
