Question 466043: A 12-foot tree casts a 16-foot shadow. How many feet tall is a nearby tree that casts a 20-foot shadow at the same time? Answer by gwendolyn(128) (Show Source):
You can put this solution on YOUR website! If the 12 foot tall tree casts a 16 foot shadow, the actual size of the tree is 3/4 the size of the shadow. Since the other tree casts a 20 foot shadow, we can infer that the actual tree is 3 fourths of this size, or 15 feet tall.
The other tree is 15 feet high.
