Write a radical for exact length of the diagonal of the 30 by 30 dance floor. simplify the radical.

Im not sure how to do this.

  • Algebra -

    What is Pythagorean theorem?

  • Algebra -

    since it's 30 by 30, the shape is a square.
    recall that the diagonal of a square is given by:
    diagonal = sqrt(s)
    where s = length of a side
    thus, the diagonal is
    sqrt(30)

    hope this helps~ :)
