Correct question:

Find the cost of painting the walls of a room if the room is 4 m 50 cm high and each side of the room is 6 m long the cost of painting is Rs 10 per sq m.​

⇒The cost of painting the wall of the room is ₹ 1080.

Explanation:

It is stated that,

Each room is 4 m 50 cm high = 4 +(50/100) m [1 m= 100 cm]

                                                 = 4.0 +0.5 m

                                                 = 4.5 m

Each room is 6 m long

Hence for each wall of the room _

Length = 6 m

Breadth = 4.5 m

Area of each wall = (Length × Breadth)

                                = (6× 4.5) m²

                                = 27.0 m²

                                = 27 m²

We know that, a room consists of 4 walls.

Total area of the walls of the room = (27×4) m²

                                                        = 108 m².

The cost of painting 1 m² is ₹ 10

Hence, the cost of painting 108 m² = ₹(108×10)

                                                          =₹ 1080.

∴ The cost of painting the wall of the room is ₹ 1080.
