Answer :

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

[tex]A=b\times h[/tex]

Then:

[tex]\begin{gathered} A=(17ft)(16ft) \\ =272ft^2 \end{gathered}[/tex]

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

[tex]272\times\text{1}.25=340[/tex]

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