    if the length of a rectangle is (x+1/x) and the width is (x+2/2) what is the perimeter of the rectangle?

    Perimeter of a rectangle = 2l+2w. Just multiply both expressions by two, and add them. That is the perimeter.

    What do you mean by weird answer? The result should be a function of x.

    Well, when you multiply the expressions, you should get Perimeter = 2(x+1/x)+2(x+2/2)

    Also, 2/2 = 1, so simplify. I'm not sure whether you mean (x+2)/2 or x+2/2

    That means you have to distribute the 2 into both functions, and add the result.
