Q. In

2016

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

377

\text{people}

/

\text{km}^{2}

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

\newline

_____

\text{people}

/

\text{m}^{2}

Convert units: Convert the given population density from people per square kilometer to people per square meter. $\newline$ Calculation: $1 \text{ km}^2 = 1,000,000 \text{ m}^2$ $\newline$ Therefore, $377 \text{ people/km}^2 = \frac{377 \text{ people}}{1,000,000 \text{ m}^2}$
Simplify fraction: Simplify the fraction to find the population density in people per square meter. $\newline$ Calculation: $\frac{377}{1,000,000} = 0.000377 \text{ people/m}^2$
