What is a hectare used for?

A hectare measures area mainly for farms, fields, and land-use statistics.

Where is the barn unit applied?

Barns are used chiefly in nuclear and particle physics to describe very small cross-sectional areas.

Is hectare an SI base unit?

No, a hectare is not an SI base unit but is accepted for use with the SI system.
