A wall is 8 feet high and 10 feet long. How much wallpaper is needed to cover it?

A = LW

A = 8 * 10

A = _______ square feet

8*10=80

To determine how much wallpaper is needed to cover a wall, you need to calculate the area of the wall. The area is calculated by multiplying the height of the wall by the length.

In this case, the wall is 8 feet high and 10 feet long. So, the area of the wall would be:

Area = height x length
Area = 8 feet x 10 feet

Multiplying 8 by 10 gives us the total area of the wall, which is 80 square feet.

Therefore, you would need 80 square feet of wallpaper to cover the entire wall.
