Question

is there the total cost of flooring a room at 40 square metre is 8640 if the length of the room is 18 M find its breadth

Answer 1

I think the cost here is out of context.

Answer 2

Answer:

12 metres

Step-by-step explanation:

Total cost of flooring room =  $8640

Given :

let total area be y,

8640 = 40( y )

y = 8640 / 40

y = 216m²

Total Area = length x breadth

216 = 18 x B

Thus, B = 12metres
