Is the particle size squared a suitable measure of area? #731

I want to find the area of an elliptical particle detected using Trackpy, and wanted to know if I could take the size squared and have that equal the area (multiplied by a constant). It says "size means the radius of gyration of its Gaussian-like profile", and I was a bit confused on what that exactly meant.
