Question 24756: A dance floor required for one persons is 9 square feet what is length and width of a dance floor if you have 100 dancers? Answer by rapaljer(4671) (Show Source):
You can put this solution on YOUR website! If each dancer needs 9 square feet, and you have 100 dancers, that would be 900 square feet. For a square area, you need the formula , or square feet.
What number times itself is 900??? Try 30! If you didn't know this you can always take the square root of both sides, and use a calculator to take the square root of 900.
or
s= side of a square, so it has to be positive, s= 30 feet.
