Problem Solving ? Jose helped his uncle plant a baby apple tree in his yard. Jose read the tag on the tree and joked, “This tree is just a baby and it’s already two feet tall!”   Jose’s uncle pointed at an oak tree in the back of the yard and said, “That tree used to be the same size when I first planted it years ago. Now it’s six times the height of this little apple tree.” Jose was wondering what the height of the oak tree was, so his uncle drew him the diagram to the right. How can the diagram that Jose’s uncle drew help Jose figure out the height of the oak tree? 2ft   Apple tree Oak tree ?
