You can put this solution on YOUR website!
Let width be x then length = X+17
\n" ); document.write( "area = 60
\n" ); document.write( "x(x+17) = 60
\n" ); document.write( "x^2+17x -60 = 0
\n" ); document.write( "(x+20)(x-3) = 0
\n" ); document.write( "x=-20, x=3
\n" ); document.write( "ignoring negative we have x = 3
\n" ); document.write( "length = 3+17
\n" ); document.write( "=20 m \n" ); document.write( "

\n" );
