What is difference between Torque and Work Done if Newton-Meter is Joule?

Torque=Force*Perpendicular distance Work =Force*displacement

The units for torque and work happen to have the same dimensions but torque and work are very different concepts. Work is a scalar and torque is a vector.

The angular equivalent of work = force*displacement is:
work = torque*angular displacement

where angular displacement is measured in radians, which is dimensionless, so the unit for torque must necessarily have the same dimension as the unit for work.
