I suggest using VLAN for each department, you can use this documentation how to configure VLAN network and also you can view here example architecture.

Once the VLAN configured you can now use the Class B IP addresses depending on your network setup, you can also use this link IP Address and Subnetting Guide.

The question wants you to understand the Class B allocation of private addressing within RFC1918. RFC1918 allocated a single class A, 16 class Bs and an entire block of 256 class Cs. To answer this question (i'm not doing what is clearly your homework for you) You need to seach for all of the address space set aside in RFC1918 and figure out which is class B. Then, using some of that address space, create subnets sufficient for networks containing 28 hosts on each network. I'm not sure if your professor/instructor is expecting you to make subnets that are just big enough to support that many users or if you are expected to allow for a resonable amount of growth. You might want to clarify.
