\n" ); document.write( "recall, the diagonal divides a rectangle into two right angle triangles; so,the diagonal \"d\" is hypotenuse, the width \"W\" and the length \"L\" are legs\r
\n" ); document.write( "\n" ); document.write( "use Pythagorean theorem to calculate the length \"L\"\r
\n" ); document.write( "\n" ); document.write( "if the diagonal \"d\" of a rectangular field is \"50m\" and its width \"W\" is \"14m\", than the length \"L\" will be:\r
\n" ); document.write( "\n" ); document.write( "\"d%5E2=L%5E2%2BW%5E2\"\r
\n" ); document.write( "\n" ); document.write( "\"L%5E2=d%5E2-W%5E2\"\r
\n" ); document.write( "\n" ); document.write( "\"L%5E2=%2850m%29%5E2-%2814m%29%5E2\"\r
\n" ); document.write( "\n" ); document.write( "\"L%5E2=2500m%5E2-196m%5E2\"\r
\n" ); document.write( "\n" ); document.write( "\"L%5E2=2304m%5E2\"\r
\n" ); document.write( "\n" ); document.write( "\"L=sqrt%282304m%5E2%29\"..you will need only positive root since the length cannot be negative\r
\n" ); document.write( "\n" ); document.write( "\"L=48m%5E2\"\r
\n" ); document.write( "\n" ); document.write( "
