Emilio found that a scarecrow that is 8 feet tall casts a shadow 15 feet long. Then Emilio noticed that a lemon tree nearby casts a shadow 30 feet long. How tall is the lemon tree?
If the tree's shadow length is 15 and you want to find the tree which is 30, you multiply by two and you have to multiply the 8 as well by two and you get 16.
