Asia dwarfs Peru: about 44,580,000 km² km² against 1,296,279 km² km². At true size Asia is about 34.4× larger — the whole of Peru fits into Asia roughly 34 times.
The old Mercator map treated both about equally (1× vs 1× inflation), so at least their relative sizes were preserved — even if both were drawn at the wrong absolute scale.
Peru fits 34× into Asia.
