of 255.255.224.0 , Which subnet would your ip address fall on?
What about 161.109.40.3 ?

Your company has a network address assigned to you
from internic. The address is 145.16.0.0. You need to divide
your network up into several departments (to contain traffic),
such as Payroll, Accounting, HR, Management, Information
Systems, & Advertising. List the appropriate network address
you will give to each department so you could configure the
Router.
