The perimeter of a rectangle is the sum of the lengths of its four sides. Which expression, where l=length and w=width, does not show this relationship?

P = 2 (l + w)

Step-by-step explanation:

If we sum the lengths of four sides of any quadrilateral then we will get its perimeter.

Now, in the case of a rectangle, the opposite sides are equally long.

Hence, in the perimeter of a rectangle, the length will be twice and the width is also twice.

If l represents the length and w represents the width of the rectangle then the perimeter will be equal to

P = 2l + 2w = 2 (l + w). (Answer)
