What is the population of Rectangleville?

76,800

Step-by-step explanation:

Given the following:

Length = 20 kilometers

Width = 12 kilometers

Population density = 320 people per sq km

Population = ?

Recall:

Area of rectangle = Length * width

Therefore,

Area of Rectangleville = 20 km * 12 km = 240km^2

Population is related to population density and Area by the formula;

Population density = population : Area

Therefore,

Population = population density * Area

Population = 320 * 240 = 76,800

Therefore, the population of Rectangleville is 76,800 people
