\n" ); document.write( "a person \"2m\" tall casts a shadow \"5m\" long\r
\n" ); document.write( "\n" ); document.write( "at the same time, a building casts a shadow \"24m\" long\r
\n" ); document.write( "\n" ); document.write( "both person and building with their shadows forming right triangle each, and triangles are similar\r
\n" ); document.write( "\n" ); document.write( "corresponding sides of similar triangles are \"proportional\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "let the height of building be \"h\", than we have\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"h%2F24=2%2F5\"...cross multiply\r
\n" ); document.write( "\n" ); document.write( "\"5h=2%2A24\"\r
\n" ); document.write( "\n" ); document.write( "\"5h=48\"\r
\n" ); document.write( "\n" ); document.write( "\"h=48%2F5\"\r
\n" ); document.write( "\n" ); document.write( "\"h=9.6\"\r
\n" ); document.write( "\n" ); document.write( "the building is \"9.6m\" tall\r
