Answer: the cost of the wallpaper per square feet is $0.6

Step-by-step explanation:

The formula for determining the area of one rectangle of the rectangular room is expressed as

Area = Length * width

Wallpaper was applied to one rectangle of a small room. 8.5 ft by 9 ft. It means that the area on which the wallpaper is applied is

9 * 8.5 = 76.5 square feet

If the total cost of wallpaper was $45.90, it means that the cost of the wallpaper per square feet is

45.9/76.5 = $0.6
