if a diagonal is drawn on a rectangle,it divides the rectangle into two right angle triangle.
\n" ); document.write( " if diagonal d =30inch
\n" ); document.write( " width w=24inch
\n" ); document.write( "lenght l=?
\n" ); document.write( "using pythagoras theorem
\n" ); document.write( " d²=L²+w²
\n" ); document.write( "therefore,
\n" ); document.write( "30²=L²+24²
\n" ); document.write( "900=L²+576
\n" ); document.write( "L²=900-576
\n" ); document.write( "L²=354
\n" ); document.write( "L=\/354
\n" ); document.write( "L=18
\n" ); document.write( "The lenght of the rectangle is 18inch \n" ); document.write( "

\n" );
