Plug in numbers: Let 1,200 = population of State X and 600 = population of State Y. Let the population concentration of State X = 12, and the population concentration of State Y = 4. The area of State X is thus

population

area

=

1200

area

= 12
→ area = 100.
The area of State Y is thus

population

area

= 600‌area = 4 → 150
area = 150. The ratio of the area of State X to the area of State Y is thus

100
