length of a rectangle is 3x-1 meters and the width is 7x+2 meters, \r
\n" ); document.write( "\n" ); document.write( "Area of rectangle = L * W\r
\n" ); document.write( "\n" ); document.write( "A= (3x-1)(7x+2)\r
\n" ); document.write( "\n" ); document.write( "=3x(7x+2)-1(7x+2)\r
\n" ); document.write( "\n" ); document.write( "=21x^2+6x-7x-2\r
\n" ); document.write( "\n" ); document.write( "=(21x^2-x-2) sq. meters
\n" ); document.write( "
\n" );
