Question

If wallpaper costs $1.25 per squared foot, how much will it cost to put new wallpaper in a room with area dimensions of 17 ft long by 16 ft wide?

Answer 1

Calculate the area of the wall using the formula for the area of a rectangle:

`A=b* h`

Then:

`\begin{gathered} A=(17ft)(16ft) \\ =272ft^2 \end{gathered}`

Since each square foot of wallpaper costs $1.25, multiply 272 times 1.25 to find the total cost of covering the rectangular wall:

`272*\text{1}.25=340`

Therefore, the total cost would be $340 for one wall.
