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.
