Answer:
They are both right
Explanation:
This is because you can do it either way.
For example, if you had a rectangle with the side length 10 and a width 5,
-Korey: you could add them to get 15 and them double them to get 30
or
-Ian: double both (5*2=10 and 10*2=20) and then add and 10+20 = 30
So they are the same
