Final answer:
B) 112 square feet. The amount of wallpaper needed to cover the wall (excluding the door) is 112 square feet.
Step-by-step explanation:
To find the amount of wallpaper needed to cover the wall (excluding the door), we need to find the area of the wall. The formula to find the area of a rectangle is length times width. In this case, the dimensions of the wall are 14 ft wide and 8 ft high, so the area of the wall is 14 ft * 8 ft = 112 square feet.
Therefore, the correct answer is B) 112 square feet.
