    x / 4 = 72 / 48

    x = 72 * 4 / 48

    x = 6

    Use the building to get the height-to-shadow ratio: 72/48 = 3/2

    woman's height/4 ft shadow = 3/2

    woman's height = 6 ft

    OK Do like this

    If 72ft casts 48 ft shadow, How much 1ft will cast = 48/72

    Now inverse it

    48/72 ft shadow cast by 1ft

    1ft Shadow will be cast by 1/(48/72) => 72/48

    4ft shadow ' ' => 72/48 * 4 = 6ft

    Cheers!!
