(A) Step $1$: Calculate the area of the square room.Side of the square room $= 3\, m = 300\, cm$.Area of the room $= 300\, cm 	imes 300\, cm = 90,000\, cm^2$.Step $2$: Calculate the area of one marble slab.Area of one slab $= 20\, cm 	imes 30\, cm = 600\, cm^2$.Step $3$: Calculate the number of slabs required.Number of slabs $= \frac{	ext{Total Area of Room}}{	ext{Area of one slab}} = \frac{90,000}{600} = 150$.Therefore,$150$ marble slabs are required.
