are these sentence correct?

[scott833]

1) We can exit by this exit.
2) Can we go out by this door?

 

[emsr2d2]

1) We can exit by this exit.
2) Can we go out by this door?

They're correct but both sound messy. In the first, repeating the word exit sounds strange. I would say:

1) Can we leave by this exit?
OR
Can we exit this way?

2) Can we leave via this door?
Can we leave by this door?
Can we leave this way?
