Answer:
4th and 6th box
Step-by-step explanation:
One of the lengths of the rectangle is s-6 because it is "6 inches shorter."
The other length is s+1 because it is "1 inch longer."
You multiply them because you want to find the area. Your equation will be (s-6)(s+1).
This equation can also be written as s^2-5s-6 using distributive property.
