Are Single Markets also free trade areas?
Free trade area means there's no customs checking goods traded within that area.

From Wikipedia:


  The European Single Market, Internal Market or Common Market is a single market which seeks to guarantee the free movement of goods, capital, services, and labour – the "four freedoms" – within the European Union (EU).


So goods are traded freely within the EU, and hence EU is an FTA.
