Your answer
-------------------
Length of a room = 5 m
Breadth of a room = 4 m
Height of a room = 3 m
Area to be whitewashed = Area out for walls + Area of ceiling
= 2(l + b)h + lb
= [{2 × (5 + 4) × 3} + (5 × 4)] m²
= [ 54 + 20] m²
= 74 m²
Then,
---------
Rate of whitewashing = Rs 7.50 / m²
Cost of whitewashing the room = Rs ( 7.50 × 74) = Rs 555
