    First convert 4 feet to inches.

    4*12=48

    So your ratio is 1:48, which means the actual airplane is 48 times longer than the drawing.

    5*48=240 inches

    The actual airplane is 240 inches, or 20 feet long.

    1 inch must be multiplied by 5 to give you 5 inches. So, you also multiply 4ft by 5 to give you 20ft. The actual airplane is 20ft long
