    Hello, lizard4!

    Find the perimieter of the given figure.
    The given figure is a rectangle showing two sides:
    Length: . \frac{x}{2x-5}
    Width: . \frac{8}{2x-5}

    P\:=\:2L + 2W, correct? . Right!

    so how do I multiply this?
    i got: x+8/(2x-5)^(2) . . . or -19 + 8/x . . . or-2+8/x
    What in the world are you doing ??


    P \;\;=\;\;2L + 2W \;=\;2\left(\frac{x}{2x-5}\right) + 2\left(\frac{8}{2x-5}\right)

    . . = \;\;\frac{2x}{2x-5} + \frac{16}{2x-5} \;\;=\;\;\frac{2x+16}{2x-5}
