We have three shapes in my study. We called them trees. The class of Tree 1 is larger than the class of tree 2 and tree 3. Also, the shape of tree 1 contains the shapes of both tree 2 and tree 3. I would like to compare them and show that tree 2 and tree 3 are contained in tree 1. Here is my try:
The class of tree 1 is larger than the one of the second and third tree, containing both of them.
The class of tree 1 is larger than the one of the second and third tree and contains both of them.
How can I compare two things and mention the ability of one of them in one sentence?
