Answer 1

C.
`\$340`

Explanation:

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* width\\=17* 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* 1.25=\$ 340`
