For convenience let's call the given side the length, so...
\n" ); document.write( "\"l=2x%2B4+\"\r
\n" ); document.write( "\n" ); document.write( "W are also given the perimeter...6x+4 and we for a rectangle, \"P=2%28l%2Bw%29+\"
\n" ); document.write( "therefore:\r
\n" ); document.write( "\n" ); document.write( "\"2%28l%2Bw%29=6x%2B4+\"
\n" ); document.write( "so we have enough information to solve for w: \r
\n" ); document.write( "\n" ); document.write( "\"2x%2B4%2Bw=3x%2B2\"
\n" ); document.write( "\"w=x-2\" \r
\n" ); document.write( "\n" ); document.write( "Now we have enough information to solve for area.
\n" ); document.write( "\"A=l%2Aw\"
\n" ); document.write( "so
\n" ); document.write( "\"A=%282x%2B4%29%28x-2%29=%0D%0A2x%5E2-8+cm%5E2\"
\n" ); document.write( "
\n" );
