​

Answer 1

Answer:

The answer for this question is

Step-by-step explanation:

The height of room = 4m 50 cm

                                = 4.5 m ( ∵ 100cm = 1m so, 50cm = 0.5m)

The length of the room = 6 m

The cost of painting = Rs.10 per sq m

∴ Area of four walls

       Area = 2× (l + b) ×h

                = 2×( 6+6) ×4.5 (∵ from question we take l=b=6m)

                = 2×12×4.5

                = 108 sq m

The cost painting the wall

   1 sq m = Rs. 10

   108 sq m = Rs ( 108 × 10)

                    = Rs.1080
