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
