Africa dwarfs Botswana: about 30,370,000 km² km² against 580,622 km² km². At true size Africa is about 52.3× larger — the whole of Botswana fits into Africa roughly 52 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 52× into Africa.
