Question

The total cost of flooring a room at the rate of Rs 85 per sq m is Rs 5100. If the length of the room is 10 m, find its perimeter.​

Answer 1

Answer:

perimeter = 32

Step-by-step explanation:

Area of the room = rs 5100/rs 85 = 60 sqm

length = 10m

breadth = (60/10)m = 6m

so the perimeter = 2(length + breadth)

                             = 2(10+6)

                             = 2*16

                             =32
