    Width is 18 inches

    Perimeter is 99 inches

    Area is 567 square inches

    Step-by-step explanation:

    The ratio of width to length is 4 : 7

    The length is 31.5 inches

    The width = (31.5 * 4) : 7 = 18 inches

    Perimeter = 2 (length + width)

    Perimeter = 2 (31.5 + 18) inches = 99 inches

    Area = length * width

    Area = 31.5 inches * 18 inches = 576 square inches.
