    Given:

    The width of a rectangle is x centimeters and its length is (x+ 2) cm.

    To find:

    The expression for the perimeter of the rectangle.

    Solution:

    We know that, perimeter of a rectangle is

    Perimeter=2(Length+Width)

    We have,

    Width = x cm

    Length = (x+2) cm

    Putting these values in the above formula, we get

    Perimeter=2((x+2)+x)

    Perimeter=2(2x+2)

    Perimeter=2(2x)+2(2)

    Perimeter=4x+4

    Therefore, the required expression for the perimeter of the rectangle is (4x+4) cm.
