You can put this solution on YOUR website!
L*W = Area
\n" ); document.write( "2L+2W = Perimeter
\n" ); document.write( "example:
\n" ); document.write( "(12x-7)*5 = Area
\n" ); document.write( "2(12x-7+2(5) = Perimeter
\n" ); document.write( ":
\n" ); document.write( "You do the others, follow this example
\n" ); document.write( "
\n" );
