Question: You are designing a subnet mask for the network. You want 12 subnets with up to 3100 hosts on each subnet. What subnet mask should you use?

ok i know how to get the hosts so i need 12 bits to get 4096 so thats why i have this mask so my new mask is /20 now because the is a class b subnet so the number of subnets are 16-20 = 4 and 4^2 = 16 so i have enough to supplie the 12 subnets

i am right?
