Well a roll of wallpaper is just a large rectangular piece of wallpaper. So you know the width and the area, so you can find the length.

L * W = A so....
L= A/W

anonymous · Answer

the width is 1 17/24 ft. the are is 28x28=784, correct

anonymous · Answer

You have the area and the width, you can find the length by using the fact that Area=lw and solve for l to give you l=Area/width to get your answer...

trouble, you don't need to square the 28....they have already given you the area which is 28
also get rid of the mixed number and make it a fraction -->41/24

divide: 28/(41/24) = 28*(24/41) = 672/41 =16.39

I did exactly what you did. My answer is 16 20/41.
