Jared wants an estimate of the height of some trees near his lake house. Use ideas of size transformationto design a plan for him to use his height to estimate accurately a tree's height without directly measuring........

I understand the concept of size transformation, I have used it a lot in paint to shrink and blow up pictures. I understand that ABCD in one onject will still equal ABCD after size transformation, however I am unsure where to begin when comparing it to a set height. Any help would be appriciated. Thank you.
