Answer: 168 people can attend the
town hall meeting.
Step-by-step explanation:
Population density is expressed as the ratio of the total number of people, N living in or occupying an area or space to the total area or space. Therefore
Population density = number of people/area
The space where the meeting will be held is 42,000 Square feet.
The population density is .004 people per square foot. This means that
0.004 = N/42000
N = 0.004 × 42000
N = 168 people
