A perimeter of a rectangle is:

They give you the width, but let's convert it to an improper fraction first:

The length is twice the width so it is:

Now, we are ready to solve, plug in values in the perimeter formula:

So, 40 is your answer.

Interpreting your expression as

when
approaches zero, the numerator approaches 3:

The denominator approaches 0, because 
Moreover, we have

So, the limit does not exist, because left and right limits are different:
