    173.6 m

    Step-by-step explanation:

    Perimeter of rectangle = 2 * length + 2 * width

    Area = 235.2m²

    Length = 2.8

    Area of rectangle: length*width

    So: 2.8*width = 235.2m²

    width = 235.2/2.8 = 84

    Use the formula for perimeter of rectangle

    So: 84*2 + 2.8*2

    Perimeter = 173.6m
