I want to know the answer to the following question:
How large is the smallest canton?
All the background I'm provided with is that "Their populations vary between 15,000 (Appenzell Innerrhoden) and 1,253,500 (Zürich), and their area between 37 km2 (14 sq mi) (Basel-Stadt) and 7,105 km2 (2,743 sq mi) (Graubünden).". Is that enough to answer the question?
