Answer:
La Paz is a bit more densely populated than Lima, since the former has a population density slightly higher than this of latter.
Explanation:
In this case, we need to know the populations and occupied area of the city. By definition, population density is the ratio of the population of the city to the occupied area in the same location.
The required information is gathered below:
La Paz (Bolivia)
Population: 1.801 million (Metropolitan area)
Occupied area: 475 square kilometers.
Population density: 3792 inhabitants per square kilometer.
Lima (Perú)
Population: 9.674 million
Occupied area: 2672 square kilometers.
Population density: 3621 inhabitants per square kilometer.
In this case, La Paz is a bit more densely populated than Lima, since the former has a population density slightly higher than this of latter.
