document.write( "Of course, if formal algebra is not required, and if the speed of reaching the solution is important -- as on a timed competitive exam -- then a quick mental solution is simple.  The sum of the length and width is 14 and the product (the area) is 40, so you are looking for two numbers whose sum is 14 and whose product is 40.  Two seconds of thought (if you are slow!) gives the dimensions as 4 and 10.<br><BR>\n" );
