If you draw a triangle from the top of the street light to the end of the woman's shadow, you get the relative heights of the woman and the street light. Let n be the heigh of the street light. Then:
\n" ); document.write( "1.62/2=n/5
\n" ); document.write( "2n=8.1
\n" ); document.write( "n=4.05m as the height of the street light
\n" ); document.write( "☺☺☺☺ \n" ); document.write( "

\n" );
