This is minor but did not seem right. We were being vectored to an ILS [Runway] 22L at JFK. Over Farmingdale (FRG) at 4;000 feet; we were cleared to descend to 3;000 feet. The Class B floor here is 4;000 feet. I have flown this pattern countless times. Normally we are kept in the Class B airspace. I said to the First Officer we need to slow to 200 kts. As I am trying to get a word in on the frequency to tell the Controller we were slowing he called us and assigned us 200 kts. I suspect this was to comply with the speed limit. So; yes; for a moment we were in excess of 200 knots below the Class B floor. What bothers me here is why were we assigned an altitude below the Class B when it was not really necessary. If a Controller takes you out of the Class B shouldn't you be advised? The frequency was too busy to ask questions.Not sure. Ask New York TRACON. Next time I'll ask to remain in the Class B.
B757-200 pilot reported being vectored out of and under Class Bravo airspace; causing a possible violation of the 200 knot speed limit.
