A township is in the shape of a rectangle that is 5 km long and 4 km wide. There are 2000 residents in the township.
What is the population density of the township?
A. 100 residents/km2
B. 125 residents/km2
C. 222 residents/km2
• D. 500 residents/km2
To find the population density of the township, we need to divide the total number of residents by the total area of the township.
Total area = length x width = 5 km x 4 km = 20 km2
Population density = Total number of residents / Total area
Population density = 2000 / 20
Population density = 100 residents/km2
Therefore, the population density of the township is 100 residents/km2 which matches with option A.
