Answer:
Tree is 16m tall.
Explanation:
The linking factor here is that as it is the same time of day, the angle of the sun will be the same.
The length of the two shadows is in the same ratio as the two heights. We are working with similar triangles.
We could use trigonometry, but similar triangles is a more direct method involving one calculation.
