3.5 m at the rate of 285 per square metre. and the answer is 16558.50​

Answer 1

Answer:

Step-by-step explanation:

l=3.8m b=4.5m h=3.5m

area of four walls of room = 2(lh+bh)

                                          = 2*3.5(3.8+4.5)

                                           =7*8.3

                                             = 58.1 m²

cost of panelling the four walls = 58.1*285

=16558.50 Rs
