Area command is made to be "vague", to give just the general idea of a player's location.
Dis command gives you the exact distance between you and the target and also tells you where to go.
If /dis cmd had location name also then new players might be able to learn places more easily.
and I exactly knew /area is vague that's why i am advising to make one, hybrid of both. majority of new players also don't know about all cmds so if they see anybody using /area then they must assume after its use, that other info could not be and if it see /dis cmd used by pupil then they will just know about the exact location of the player but he will not get that which location was? what was its name? because many other features represent places as names. So it will be easy to learn places? And I think two cmds about same subject is distracting

I think this is kinda unnecessary given that we have a minimap too. Learning the map isn't that hard and most people know it perfectly.
but not new and majority of people.
Its kind of useless, you can get the location by /area and the map also provide the blip so you can easily locate the suspect without using the distance.
While chasing a criminal a cop find many yellow blips around so they dont get exactly which one is his target.
