The perimeter of a rectangle is 16 inches. the equation that represents the perimeter of the rectangle is 2l + 2w = 16, where l represents the length of the rectangle and w represents the width of the rectangle. which value is possible for the length of the rectangle?

You haven't listed the choices that go with the question, so
it's really tough to guide you toward the correct choice.

Sticking with whole numbers, here are all possible dimensions
of the rectangle:

Length  Width  Perimeter
     7            1           16
     6            2           16
     5            3           16
     4            4           16

Uneed to add them up 27+18+23=68
