    drawing length = 7 cm; actual length = 200 cm

    Step-by-step explanation:

    The ratio is 1 cm in the drawing is 30 cm in actuality.

    If the drawing is 5 cm, multiply by 5

    5*1 to get the 5 cm drawing and 5*30 to 150 cm in actual length

    5cm drawing = 150 cm actual

    11cm drawing multiply by 11

    11*1 = 11 and 11*30 = 330 cm

    11 cm drawing = 330 cm actual

    7cm drawing multiply by 7

    7*1 = 7 and 7*30 = 210 cm

    7 cm drawing = 210 cm actual

    8cm drawing multiply by 8

    The one that is not correct: drawing length = 7 cm; actual length = 200 cm

    8*1 = 8 and 8*30 = 240 cm

    8 cm drawing = 240 cm actual
