A man wants to remove a tall pine tree from his yard. Before he goes to home depot, he needs to know how tall an extension ladder he needs to purchase. He measure the shadow of the tree to be 225 feet long. At the same time he measures the shadow of a 4 foot stick to be 3 feet. Approximately how tall is the pine tree?
h/225 = 4/3
h = 300 ft
So, how long a ladder does it take to cut down a 300' tree?
Maybe he'd be better off to measure the diameter of the tree, so he can get a saw of appropriate size.
