Step-by-step explanation:

We have,

Length of room = 4.5 m

Breadth of room = 3.2 m

Hence, area of the room = Length*Breadth

Area of room = 14.4 m²

Area of door = 1.5 * 1 m = 1.5 m²

As the door is leaved, the area which is to painted is 14.4-1.5 = 12.9 m²

Therefore the cost of painting the wall leaving the door is 12.9*420 = Rs. 5418
