Original: 11 feet
\New: 25 feet
\Since the new feet is greater than the original, this is a percent of increase.
\The amount of change = New feet – Original feet.

Let r be the percentage of increase.
\Use the original number, 11 as the base.
\The percent proportion is ![\"\"](\"/test/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=4c5a2948e14cd6a7a2f438a06cece400.png\")

To solve for r, first find the cross products.
