Work is a measure of the energy transferred.
Explanation:
In physics, the work is a measure of the energy transfer.
An example of work done is when a force is pushing an object. The work done by the force on the object is given by:
where :
F is the magnitude of the force
d is the displacement
is the angle between the direction of the force and of the displacement
When the force is applied on the object, work is done, and the object accelerates, gaining kinetic energy. This means that energy has been converted from another form into kinetic energy of the object. Therefore, work is also a measure of the energy transferred (in this case, in fact, the work done is equal to the kinetic energy gained by the object): therefore, it has the same units of the energy, Joules (J).

Answer:
The intensity will be 1/9 as much.
Explanation:
The intensity of the light or any source is inversely related to the square of the distance.
Now according to the question the distance is increased by three times than,
Therefore,
Therefore the intensity will become 1/9 times to the initial intensity.
