    Answer:

    1000 cm.

    Explanation:

    To obtain the estimated tree height :

    (Height of rod / length of rod shadow) = (height of tree / length of tree shadow)

    Substituting values into the formula :

    (150cm / 120 cm) = (height of tree / 800 cm)

    Using cross multiplication :

    Height of tree * 120 = 150 * 800

    Height of tree = (150 * 800) / 120

    Height of tree = 120,000 / 120

    Height of tree = 1000

    Hence, estimate height of tree = 1000 cm
