Question

The total cost of flooring a room at Rs.8.50 per square metre is Rs. 510. If the length of the room is 8 metres find its breadth.

Answer 1

Given that,
                 
                Cost of flooring per square metre  = 8.50 rupees.
                Total cost of flooring of room = 510 rupees
                 Therefore, Area of the room =510 ÷8.50 =60
                  there fore we know that area = length *breadth
                   if length of the room = 8 meteres then breadth = area/length = 60m²/8m = 7.5m

Answer 2

Answerable

Step-by-step explanation: Cost of flooring per square meter  = 8.50 rupees.

               Total cost of flooring of room = 510 rupees

                Therefore, Area of the room =510 ÷8.50 =60

                 there fore we know that area = length *breadth

                  if length of the room = 8 meters then breadth = area/length = 60m²/8 = 7.5m
