To find the area of a rectangular shape, we need to have the length and width of the shape.
Here the room is rectangular in shape.
The length of the room is 60 meters and lets say the width of the room is 'w' meters.
The area of room is given which is 2,400 square meters.
The area of rectangle is given by:

Now, plugging the values of the length and width, we get:


Solving for width, we get:
meters.
So, the width of the rectangular room is 40 meters.
