Question

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

Answer 1

2l + 2w = 16   
2(l+ w)  = 16    Divide both sides by 2
l + w =  16/2

l + w  =  8

So for example the length l could be 5 and the width could be 3.
Length could be 5.

Length l could be 6 and width be 2.
Length could be 6 as well.
