A. $1,215.84
B. $806.56
C. $807.60
D. $1,216.94

Answer 1

The cost of installing a strip of wallpaper around the room is $2829.16.

Step-by-step explanation:

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 is given by the formula P = 2(l + w), where l is the length and w is the width.

In this case, the length is 16 feet and the width is 12 feet, so the perimeter is 2(16 + 12) = 2(28) = 56 feet.

Next, we multiply the perimeter by the cost per foot of the wallpaper.

The cost per foot is $50.61, so the total cost is 56 feet * $50.61/foot = $2829.16.

Therefore, the cost of installing a strip of wallpaper around the room is $2829.16.
