Answer:
Step-by-step explanationthe 2 represents the 2 other side of the rectangle
Let's take the first derivative:
Notice that we can write this as:
By taking the derivative of both sides 
times, we get:
This means that each time you take a derivative, a factor of 
will appear. So we conclude that:
Taking 
and 
, we get:
So we finally get:
