This can be set up as a proportion, as the proportion of the height of an object to its shadow will be the same for all objects.

\n" ); document.write( "\n" ); document.write( "6:17 = x:102, where x is the height of the tree. This can also be written as
\r
\n" ); document.write( "\n" ); document.write( " $\"6%2F17+=+x%2F102\"$ .
\n" ); document.write( " $\"102%2A6+=+17%2Ax\"$
\n" ); document.write( " $\"612+=+17%2Ax\"$
\n" ); document.write( " $\"612%2F17+=+x+=+36\"$
\r
\n" ); document.write( "\n" ); document.write( "The tree is 36 feet tall. \n" ); document.write( "
