Asia dwarfs Botswana: about 44,580,000 km² km² against 580,622 km² km². At true size Asia is about 76.8× larger — the whole of Botswana fits into Asia roughly 76 times.
The old Mercator map treated both about equally (1× vs 1.2× inflation), so at least their relative sizes were preserved — even if both were drawn at the wrong absolute scale.
Botswana fits 76× into Asia.
