    Length = 14m

    Width = 12m

    Step-by-step explanation:

    The length of a rectangle is 2m greater than the width.

    The area of the rectangle = 168m²

    Let's say the width is x meters.

    The length will be (x + 2) meters.

    Area of a rectangle = length * width

    x (x + 2) = 168

    x² + 2x - 168 = 0

    Solving x by applying the quadratic formula we get;

    x = 12 or - 14

    Since the width cannot be negative, we take 12 meters to be the dimensions of the width.

    The length = 12 + 2 = 14 meters.
