‘To be concentrated’ usage

Recently I have heard many people say that somebody needs ‘to be concentrated’ on something.

Am I right in saying that this is being used incorrectly?

Solution 1:

Collins Dictionary has the following usage note on concentrate on and be concentrated on:

If you concentrate on something, you give special attention to it, rather than to other things.

Be Careful!

Don't say that someone 'is concentrated on' something.

Be concentrated has the following usage, as suggested by M-W:

to be mainly found (in a place):

• The population is concentrated near the coast. Power was concentrated in the hands of a few rich men.
