    You can set up two ratios (a proportion) that relate the lookout to its shadow.

    Height of tower / shadow length = height of tree / shadow lenght

    Tree

    height = 8 yards.

    Shadow length = 15 yards.

    Tower

    Height of tower = ?

    Shadow = 45 yards

    8/15 = x / 45 Cross multiply

    8 * 45 = 15 x multiply the left

    360 = 15 x Divide by 15

    360 / 15 = x

    x = 24

    The tower is 24 yards high.
