    Answer:

    10 feets

    Step-by-step explanation:

    Given that:

    Road sign shadow (Rs) = 4 feets

    Height of man (Hm) = 6

    Man shadow (Ms) = 2.4 feets

    Height of road sign (Hr) = x

    Height of road sign / shadow of road sign = height of man / shadow of man

    Hr/Rs = Hm / Ms

    x / 4 = 6 / 2.4

    Cross multiply :

    4*6 = 2.4*x

    24 = 2.4x

    x = 24 / 2.4

    x = 10 feets

    Hence, height of road sign = 10 feets
