Your question is too open. It will depend on the performance, architecture, type of capacitors you are going to use, etc..

The best way is to check some old design, look at their specs and area, you will have a general feeling.

one thing is for sure.in sigma delta ADC modulator occupies less area than what the decimator occupies.toatl area also depends on of which order ADC is being used.
