Question

total cost of flooring a room at Rs.17 per square is rs.1020. if length of room is 8m. find its breadth

Answer 1

Answer:

Step-by-step explanation:

IF THE DIMENSIONS OF TILE IS 1m X 1m

total cost of flooring = rs.1020

price of one square tile = rs.17

therefore number of tiles = 1020/17

                                       = 60m²

⇒area of rectangle = length x breadth

⇒60 = 8 * breadth

⇒breadth = 60/8

               = 7.5m

Answer 2

Area of perimeter of a rectangle is 2(l+b).

Area of perimeter =1020/17=60

Now 2(l+b)=60

L+b=30

8+b=30

B=22
