width = x
\n" ); document.write( "length = 3x
\n" ); document.write( "perimeter is 2x + 2(3x)= 24
\n" ); document.write( "2x+6x=24
\n" ); document.write( "8x=24
\n" ); document.write( "x=24/8
\n" ); document.write( "x=3
\n" ); document.write( "width = 3 ft
\n" ); document.write( "length = 3*3 = 9 ft
\n" ); document.write( " \n" ); document.write( "
\n" );
