Answer 1

Stanley will need 22.1 strips of wallpaper if he uses 20 square feet of wallpaper

Answer 2

21 strips

Explanation:

Stanley has a total area on his bathroom = 450 square feet.

Each strip of wallpaper covers between = 20 to 24 feet²

Average area covers each strip = (20 + 24)/2 = 22 feet²

In order to estimate the number of strips of wallpaper Stanley will need, we have to divide total area by the area of each strip

=
`(450)/(22)` = 20.45 strips ≈ 21 strips

Stanley will need 21 strips.
