Brazil dwarfs Libya: about 8,499,400 km² km² against 1,626,369 km² km². At true size Brazil is about 5.2× larger — the whole of Libya fits into Brazil roughly 5 times.
Brazil sits in South America, Libya in Africa. On the old Mercator map the latitude gap distorted how large each felt beside the other; at true size the answer is simply 5.2×.
The old Mercator map treated both about equally (1× vs 1.3× inflation), so at least their relative sizes were preserved — even if both were drawn at the wrong absolute scale.
Libya fits 5× into Brazil.
