							A vector quantity has a direction and a magnitude, while a scalar has only a magnitude. You can tell if a quantity is a vector by whether or not it has a direction associated with it. Example: Speed is a scalar quantity, but velocity is a vector that specifies both a direction as well as a magnitude
work has no direction hence it is scalar

Dear student 
Hope you understand vector and scalar , 
But here is the resion why work s scalar quantity 
work done due to displacement caused by a force is a scalar quantity. The dot product of vector quantities is always scalar which means it is has only magnitude and no direction.
Hope this helps 
Good Luck
