Question

In 2016, the city of Rio de Janeiro had a population density of 5377 people/km^2

What was the population density of Rio de Janeiro in people per square meter?

Answer 1

Answer: The population density was 0.005377 people per square meter.

Explanation:

Answer 2

`5377 (people)/(km^2)`

And we want to provide this population density in
`(people)/(m^2)`

We know that 1km =1000m, so then we can use this fact and we can do the conversion:

`5377 (people)/(km^2) *(1km^2)/((1000m)^2) = 0.005377 (people)/(m^2)`

Explanation:

For this cae we have the following population density:

`5377 (people)/(km^2)`

And we want to provide this population density in
`(people)/(m^2)`

We know that 1km =1000m, so then we can use this fact and we can do the conversion:

`5377 (people)/(km^2) *(1km^2)/((1000m)^2) = 0.005377 (people)/(m^2)`
