To find the total area to be distempered, we need to calculate the area of the walls and subtract the area of the doors, windows, etc.

The area of the walls can be calculated by finding the perimeter of the room and multiplying it by the height of the room.

Perimeter of the room = 2 * (length + width) Perimeter of the room = 2 * (8m + 7.6m) Perimeter of the room = 2 * 15.6m Perimeter of the room = 31.2m

Area of the walls = Perimeter of the room * height of the room Area of the walls = 31.2m * 3.5m Area of the walls = 109.2m²

Now, we need to subtract the area of the doors, windows, etc. which is given as 25m².

Total area to be distempered = Area of the walls - Area of doors, windows, etc. Total area to be distempered = 109.2m² - 25m² Total area to be distempered = 84.2m²

Therefore, the total area to be distempered is 84.2 square meters.
