A rectangle room measures 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
14*12*.90 = ?
Oops. I figured the cost of covering the ceiling (or floor)
For a strip, we need twice the length+width, so
2(12+14)*.90 = ?
(12*2)+(14*2)*.90=$36
Nope
To find the cost of installing a strip of wallpaper around the room, we need to first calculate the perimeter of the room. The perimeter of a rectangle can be found by adding the lengths of all four sides.
Given that the dimensions of the room are 14 feet by 12 feet, the perimeter can be calculated as follows:
Perimeter = 2 * (Length + Width)
Perimeter = 2 * (14 + 12)
Perimeter = 2 * 26
Perimeter = 52 feet
Now, we have the total length of the wallpaper required, which is 52 feet. We can multiply this by the cost per foot to find the total cost of the wallpaper.
Cost of wallpaper = Total length x Cost per foot
Cost of wallpaper = 52 feet x $0.90/foot
Cost of wallpaper = $46.80
Therefore, the cost of installing a strip of wallpaper around the room would be $46.80.
