I need help developing a sub-netting scheme (Urgent)

[mlgporky3470]

So I have been trying to develop a subnetting scheme for some time now, but I don't exactly know what to do with the information that was given. If someone could help me do this, it would be a great help.

What was given is the C class address (200.10.10.0), the names of the offices (routers), and the usable subnets as shown in part e).

I would really like it if someone could walk me through or show me how to do the following questions on the attached image as soon as possible.

Thank you very much.

Has the test finished yet?

It isn't a test, it's just a practice assignment to test if we knew any of that. I don't really know how to do it so we were allowed to look online for help which is why I posted it here.

And yes, we can still work on it.
