ANSWER
Length, breadth and height of a room are 5 m, 4 m and 3 m.
Area of four walls of the room =2h(l+b)
=2×3(5+4)
=6(9)
=54 sq m
Area of the ceiling =l×b
=5×4
=20 sq cm.
Total area of the four walls and the ceiling of the room
=54+20
=74 sq cm
Cost of white washing = Rs 7.50 per sq m
Total cost of white washing =74×7.50= Rs 555
