Hey guys, could you help me do 4.21? I do not understand the method to do this, and it is not related, from what I see, about right triangles. Can you guys help? Thanks.

Here's a hing that may help: Try to cut right triangles. The diagram used for the proof of the Pythagorean Theorem may give you an idea of where to cut.
