Answer:
LSA of room =4a×2
=4(18)×2
=1296m×2
Area of windows and room =20% of 1296m×2
=259.2m×2
Area left=1036.8m×2
=1036.8/18=57.6 of litres
We can conclude that:
LSA of room 1295m×2
Area of windows and room=259.2m×2
Area left 1036.8m×2
paint 57.6 litres

Answer:
Ceiling = 6x5 = 30m^2
two opposite walls (length of room)=6x3x2=36m^2
two opposite walls (breadth of room)=5x3x2=30m^2
Total area - door and windows = 30+30+36–14=82m^2
