    5600 dollars

    Step-by-step explanation:

    The first thing we must do is calculate the area of the rectangle since the value is given per unit area.

    They give it per square centimeter, therefore we must pass the measurements from meters to centimeters, knowing that 1 meter is 100 centimeters:

    4m * 100cm / 1m = 400cm

    5m * 100cm / 1m = 500cm

    Now the area would be:

    A = 400 * 500 = 20000

    20000 cm ^ 2 would be the area of the rectangular wall, we calculate the value like this:

    20000 * 0.28 = 5600

    In other words, it has a value of 5600 dollars.
