\n" ); document.write( "Here is a picture....

\n" ); document.write( "

\n" ); document.write( "The slope of line AC is 7/4, so we can find the height of the triangle, CO:

\n" ); document.write( "\"7%2F4+=+h%2F9\"
\n" ); document.write( "\"h+=+63%2F4\"

\n" ); document.write( "Since OF is 8, CF is 63/4-8 = 31/4.

\n" ); document.write( "Then, since triangles CAB and CDE are similar, we can find the length of DE:

\n" ); document.write( "\"%2831%2F4%29%2Fx+=+%2863%2F4%29%2F18\"
\n" ); document.write( "\"x+=+62%2F7\"

\n" ); document.write( "Answer: the second floor is 62/7 feet wide.
