Answer 1

Answer:

C. $\ 340$

Given wallpaper costs $\ 1.25$ per square foot.

Also, the dimension of the room is $17\ ft$long by $16\ ft$ wide.

First, we will find the area of the room.

The room is in a rectangular shape.

So, the area of rectangle would be

       $length\times width\\=17\times 16\\=272\ ft^2$

Now, we will multiply this area with the cost of wallpaper.

As the cost of wallpaper is $1.25 per square foot.

The total cost of wallpaper for $272\ ft^2$ would be $272\times 1.25=\ 340$
