We are given the population of Tokyo, $33,200,000$, and its land area, $6,993$ square kilometers. We need to find the population density of Tokyo, which is the population per square kilometer, and round it to the nearest whole number.

1. Problem Description

We are given the population of Tokyo, $33,200,000$, and its land area, $6,993$ square kilometers. We need to find the population density of Tokyo, which is the population per square kilometer, and round it to the nearest whole number.

2. Solution Steps

To find the population density, we divide the population by the area:

$Population\ Density = \frac{Population}{Area}$

$Population\ Density = \frac{33,200,000}{6,993}$

$Population\ Density \approx 4747.5$

Rounding to the nearest whole number gives $4748$.

3. Final Answer

The approximate population density of Tokyo is $4748$ people per square kilometer.
