I'm not sure how you determine what "correct" is but the biggest comment
I would make is that best-practice suggests that you separate output
from calculations. So it would be better for your function to return
the area and then the caller of the function to print the result.

Another point is that in your call to print you convert area to
a string and add it to the other string. But print() does all
of that for you, you only needed to write:

print("The area is", area)

The only other style issue I can see is that your comment
is not very helpful, it simply tells us what the code already
says. Comments should explain why things are the way they
are, not simply repeat the code. In a function this trivial
there should not be any need for comments, good variable
names should suffice.
