Carpeting costs $20 per square yard. You carpeting a room that has a width of 15 feet for $800. What is the length of the room in feet?

Math  Ms. Sue, Tuesday, August 26, 2008 at 10:58am
First, find out the number of square yards in the room by dividing: $800/20 = 40 square yards
Then, change 15 feet to 5 yards.
Divide: 40/5 = 8 yards wide
Change 8 yards into feet.

First, calculate length (L) in yards. Convert the 15 feet into yards.
$20(L * 5) = $800
Once you find L, multiply that by 3 to get the answer in feet.
I hope this helps. Thanks for asking.
