There are many online sites that provide tools to perform subnet calculations that you can find by searching on "subnet calculator" or "subnet calculator cidr". E.g., go to CIDR / VLSM Supernet Calculator and put 172.16.0.0 in the IP address field and then select 255.255.240.0, which corresponds to a /20, in the CIDR netmask field. Or, specifically for 172.16.0.0/20 at IP Calculator. There are also online courses that will teach you how to perform such calculations yourself, e.g., Udemy offers Subnetting Made Super Simple (current cost $15 USD) and other courses on the topic.
