Question

A bedroom is 10 ft by 12 how much does it cost to wallpaper this room if the wallpaper costs 1.53 per ft?

Answer 1

If the room is 10 by 12 that means each wall is 10 by 12 (I'm assuming) so the area of each wall is 120 ft and since there are 4 of them the total area of the walls is 480 ft and if wallpaper costs 1.53 per ft, it costs 480 * 1.53 or $734.40

Hope this helps
