Answer 1

Step-by-step explanation:

Given,

length×breadth×height of room=3.8×4.5×3.5m

Lateral surface area of room=2h(l+b)

=2×3.5(3.8+4.5)

=7× 8.3

=58.1 metre sqaure

now cost of panelling=₹285 per square metre

=285×58.1

=16558.50

So, the cost of panelling the four walls of the room at the rate of ₹285 per square metre is ₹16558.50
