    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
