For a rectangle,
\n" ); document.write( " $\"A=L%2AW\"$
\n" ); document.write( " $\"L%2AW=128\"$
\n" ); document.write( "In this case,
\n" ); document.write( " $\"L=2W\"$
\n" ); document.write( "Then,
\n" ); document.write( " $\"2W%2AW=128\"$
\n" ); document.write( " $\"W%5E2=64\"$
\n" ); document.write( " $\"W=8\"$ $\"cm\"$
\n" ); document.write( "Then,
\n" ); document.write( " $\"L=16\"$ $\"cm\"$ \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
