Q. In

2016

, the city of Rio de Janeiro had a population density of

5377 \frac{\text { people }}{\mathrm{km}^{2}}

.

\newline

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

\newline

\square

\frac{\text { people }}{\mathrm{m}^{2}}

Convert units: We need to convert the population density from people per square kilometer to people per square meter. $\newline$ $1$ square kilometer is equal to $1,000,000$ square meters.
Calculate density: To find the population density in people per square meter, we divide the population density in people per square kilometer by the number of square meters in a square kilometer. $\newline$ Population density (people/m $^2$ ) = Population density (people/km $^2$ ) / $1,000,000$
Perform division: Now we perform the calculation using the given population density of Rio de Janeiro. $\newline$ Population density (people/m^$2$) = $\frac{5377 \, \text{people/km}^2}{1,000,000}$
Final result: Performing the division gives us the population density in people per square meter. $\newline$ Population density (people/m^$2$) = $0.005377$ people/m^$2$
