For this case we have that by definition the area of a rectangle is given by:

Where
- <em>w: width of the rectangle
</em>
- <em>l: length of the rectangle
</em>
The area of the original rectangle is given by:

The area of the new rectangle is given by:

Therefore, the original area increases with a factor of 9.
Anwer:
the original area increases by a factor of 9.
