Answers
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.
