Question

wallpaper was applied to one rectangular wall of a large room. the dimensions of the wall are shown below. if the total cost of the wallpaper was $771.12 what was the cost in dollars of the wallpaper per square foot?

Answer 1

Hi there!
First, we need to find the area of the wallpaper.
42 × 25.5 = 1071
Now, we divide 771.12 by 1071.
771.12 ÷ 1071 = 0.72
So, the wallpaper costs 0.72 dollars per square foot.
Hope this helps!
