Answer:
Dimension of room = (15×10×3)m.
Two doors dimensions = (2m×1.5m).
Three windows dimensions =(1.6m×0.75m).
Cost for distempering = ₹6.
Room= 150m²( l×b)
Doors= 3m² ; 3×2=6m² ( As two doors are there ).
Windows = 1.2m² ; 1.2×3=3.6m²( As three " " " ).
Area of walls = Area of Room - Area of Doors + Windows.
= 150 - 6 + 3.6
= 147.6m2.
Cost for Distempering = 6 × 147.6 = ₹885.6
