Answer 2

Answer:

I think u mean 7.50 per m instead of 37.50 per m!

Here goes the solution!

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.

Cost of white washing = Rs 7.50 per sq m

Total cost of white washing =74×7.50= Rs 555
