Africa dwarfs Myanmar: about 30,370,000 km² km² against 662,746 km² km². At true size Africa is about 45.8× larger — the whole of Myanmar fits into Africa roughly 45 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.
Myanmar fits 45× into Africa.
