    6, 8 and 10 cm

    Step-by-step explanation:

    Sum the [arts of the ratio, 3 + 4 + 5 = 12 parts

    Divide the perimeter by 12 to find the value of one part of the ratio.

    24 : 12 = 2 cm ← value of 1 part of the ratio, thus

    3 parts = 3 * 2 = 6 cm

    4 parts = 4 * 2 = 8 cm

    5 parts = 5 * 2 = 10 cm
