Scalar quantity are those which have only magnitude but no direction. For example : Distance, speed, mass etc. In other words, work due to displacement caused by a force is a scalar quantity. The dot product of vectors quantities is always scalar which means it is has only magnitude and no direction.

Answer:

Work is a scalar quantity because it is the dot product of two vectors (Force and displacement). Dot product of two vectors becomes scalar quantity. So, work done has only magnitude but not direction.
