x-4

Step-by-step explanation:

The area of a rectangle can be expressed as the width multiplied by the length. Therefore, you can work backwards to find the length by dividing the area by the width. x^2-16 factors out to be (x-4)(x+4), which when divided by (x+4) yields the length of the rectangle to be (x-4). Hope this helps!
