Hi,

Let the length be x. Breadth will be 2x. Let height be y.
Now we know that floor carpeting costs 175.50. So equate it to the area of floor multiplied by per m^2 rate to get x.

Now u have x, i.e. u have length as well as breadth. Use the surface area of cuboid formula to get y. Remember to subtract the area of door and windows.
