To find the total cost of installing wallpaper around the room, we need to find the perimeter of the room and then multiply it by the cost per foot of the wallpaper.
The perimeter is the distance around the outside of the room, which can be found by adding up the lengths of all four sides. For a rectangular room with sides of length a and b, the perimeter P is:
P = 2a + 2b
In this case, a = 14 feet and b = 12 feet, so:
P = 2(14) + 2(12) = 28 + 24 = 52 feet
So the total cost of installing wallpaper around the room would be:
52 feet x $0.90/foot = $46.80
Therefore, the cost of installing a strip of wallpaper around the room is $46.80.
A rectangular room measure 14 feet by 12 feet find the cost of installing a strip of wallpaper around the room if the wallpaper costs $0.90 per foot
