    3 ft by 3 ft

    Step-by-step explanation:

    The minimum dimensions will be those of a square with an area of 9 ft².

    The formula for the area of a square is

    A = l² Substitute the area

    9 = l² Take the square root of each side

    l = 3

    The minimum dimensions are 3 ft by 3 ft.
