**Reiny**, Tuesday, December 16, 2008 at 1:25am<<..The distance from the end point to the short tree is 3m >>

the distance of what? The shadow?

(That is the usual case in these kind of problems)

If it is the shadow, make a diagram showing the small tree and its shadow, and the larger tree and its shadow.

You will have two similar triangles, (the rays of the sun come in parallel to each other, resulting in equal angles)

Let the height of the tree be h m, set up a ratio, cross-multiply and solve for h
