Answer: correct choice is B.
The mean is 23 because it is the middle number
You have 4 walls, 2 with length 12 feet, 2 with length 15 feet and each of them has a height of 12 feet
so you sum all the lengths and then multiply it by the height to get the total area
total length=2*(12+15)
=2*(27)
=54
total area=total length*ceiling height
=54*12
=648 feet^2 to cover all walls with wallpaper
