Let the width be x
\n" ); document.write( "And the length be 2x-2
\n" ); document.write( "Perimeter=50
\n" ); document.write( "Formula for perimeter is
\n" ); document.write( " $\"P=2%28l%2Bw%29\"$
\n" ); document.write( " $\"50=2%282x-2%2Bx%29\"$
\n" ); document.write( " $\"50=2%283x-2%29\"$
\n" ); document.write( " $\"50=6x-4\"$
\n" ); document.write( " $\"54=6x\"$
\n" ); document.write( " $\"x=9\"$
\n" ); document.write( "width=9cm \n" ); document.write( "
