The length of a rectangular carpet is 6 feet greater than twice its width. If the area is 72 square feet, find the carpet's length and width.

  • College Algebra -

    w(2w+6) = 72
    2w^2 + 6w - 72 = 0
    w^2 + 3w - 36 = 0
    w = 3/2 (√17 - 1)

    Odd answer. These usually involve integers. Typo?
