A living room is 15 ft x 19 ft. The walls of the room are 8.5 ft tall.
Calculate the total area of one wall?
How many rolls of wallpaper will you need to cover the wall. One roll will cover 44 square feet
What will be the cost of the wallpaper? ($14.99 for a pack of 2 rolls)
The total area of all walls = [(15*8.5)+(19*8.5)+(15*8.5)+(19*8.5)] square feet
= 578 square feet
[It is impossible to compute the area of one wall as they are of different areas and here is no indication of any specific wall]
Here, one roll of wallpaper can cover 44 square feet.
Therefore, required number of rolls is = (578/44) 14.
Hence, 14 rolls of wallpaper i will need to cover all walls.
Now, the cost of 14 rolls of walpaper is = $(14.99*14/2) = $104.93
Therefore, the cost of the wallpaper is $104.93
