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

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.

To find the cost of installing a strip of wallpaper around the room, we need to calculate the perimeter of the room.

Perimeter of a rectangle = 2 × (length + width)

Given:
Length of the room = 14 feet
Width of the room = 12 feet

Calculating the perimeter of the room:
Perimeter = 2 × (14 feet + 12 feet)
Perimeter = 2 × 26 feet
Perimeter = 52 feet

Now, we can multiply the perimeter by the cost per foot of wallpaper to find the total cost.

Cost of installing the wallpaper = Perimeter × Cost per foot
Cost of installing the wallpaper = 52 feet × $0.90 per foot
Cost of installing the wallpaper = $<<52*0.90=46.80>>46.80

Therefore, the cost of installing a strip of wallpaper around the room would be $46.80.
