    The unknown scale factor above is calculated by dividing the true value of the length of the banner by the length in the photograph. If we take the first dimension that is 8 inches only in photograph but 12 feet in the banner.

    scale factor = (12 ft) (12 inches / 1 ft) : 8 inches

    scale factor = 18

    Therefore, the scale factor is 18:1. The answer to this item is letter D.
