    Part (A)

    (1 cm)/(20 cm) = (6 cm)/(x cm)

    1/20 = 6/x

    1*x = 20*6

    x = 120

    120 cm = 120/100 = 1.2 m

    Answer:  1.2 m

    =========================================================

    Part (B)

    2.2 m = 2.2*100 = 220 cm

    (1 cm)/(20 cm) = (x cm)/(220 cm)

    1/20 = x/220

    1*220 = 20*x

    20x = 220

    x = 220/20

    x = 11

    Answer: 11 cm
