#480 cm^2#

Explanation:

Just like in the previous example, this ratio is only in the one-dimensional sense. To bring it to the two-dimensional sense, raise the one-dimensional scale factor by a power of #2#. When you do this, you get a two-dimensional scale factor of 16. Now, just multiply the area by the two-dimensional scale factor, and you will get #480 cm^2#. Hope this helps.
