Arectangular room measures 14 feet by 10 feet. find the cost of installing a strip of wallpaper around the room if the wallpaper costs $0.72 per foot.

The cost of installing a strip of wallpaper around the room would be $100.80

Step-by-step explanation:

1. The formula for a rectangle's area is A = l x w. The "l" means length and the "w" means width. 14 is the length and 10 is the width, so that should leave you with A = 14 x 10.

2. When you multiply 14 by 10, you should get A = 140.

3. Since wallpaper costs $0.72 per foot, all you want to do is multiply 140 by $0.72 and you should end up with $100.80 as a result.
