    Total surface area of the room=2(lh+lb+hb)m 2 =2[9×6.5+9×8+8×6.5]m 2 =365m 2 Area of the door =l×b=2×1.5=3m 2 Area of the windows=l×b=1.5×1=1.5m 2 ∴ Surface area of walls=TSA of room −Area of door−Area of windows =365−3−1.5=360.5m 2 Cost of whitewashing per square meter=Rs. 6.40 ∴ Cost of whitewashing the walls=Rs. 6.40×360.5 =Rs. 2307.2.
