To find the cost of the wallpaper per square foot, we need to divide the total cost of the wallpaper by the total area it covers.
First, let's calculate the area of the wall. The area of a rectangle can be found by multiplying its length by its width.
Area = Length * Width
Area = 42 ft * 25.5 ft
Area = 1071 ft²
Now, we can determine the cost per square foot by dividing the total cost of the wallpaper by the area of the wall.
Cost per square foot = Total cost / Area
Cost per square foot = $771.21 / 1071 ft²
To calculate the cost per square foot, we simply divide the total cost of the wallpaper by the area of the wall.
Cost per square foot ≈ $0.7209
Therefore, the cost of the wallpaper per square foot is approximately $0.7209.
