Given Area of Rectangle as Length(L) x W (Width)
\n" ); document.write( "L = x
\n" ); document.write( "W = (x - 9cm)
\n" ); document.write( "Area = 190 square cm\r
\n" ); document.write( "\n" ); document.write( "190 = x(x - 9)
\n" ); document.write( "190 = x^2 - 9x
\n" ); document.write( "x^2 - 9x = 190
\n" ); document.write( "x^2 - 9x - 190 = 0
\n" ); document.write( "x^2 - 19x - 10x - 190 = 0
\n" ); document.write( "x(x - 19) - 10(x - 19) = 0
\n" ); document.write( "(x - 19) (x - 10) = 0
\n" ); document.write( "x = 19, x = 10\r
\n" ); document.write( "\n" ); document.write( "Length = 19
\n" ); document.write( "Width = 10
\n" ); document.write( "
\n" );
