Given:

Wallpaper was applied to one rectangular wall of a large room. The dimensions of the wall is 42 feet and 25.5 feet.

Total cost of wallpaper was $771.12

Required:

What was the cost, in dollars, of the wallpaper per square feet.

Step-by-step explanation:

We know the area of rectangle is length multiplied by breadth.

Here, we have


\begin{gathered} A\text{rea of wall =}42*25.5 \\ =1071 \end{gathered}

Now,

The cost of wallpaper per square feet is


\begin{gathered} =(771.12)/(1071) \\ =0.72 \end{gathered}

Answer:

Hence, $0.72 is the answer.
