document.write( "Hi,
\n" );
document.write( "Rectangle: width x  and length(2x-5), area = 150ft^2, find Perimeter
\n" );
document.write( "
\n" );
document.write( "A = x(2x-5) = 150f^2
\n" );
document.write( "   2x^2 -5x - 150 = 0
\n" );
document.write( "   (2x +15)(x -10) = 0   x = 10ft  (tossing out negative solution for unit measure
\n" );
document.write( "Rectangle: width of 10ft, length of 15ft
\n" );
document.write( " P =   50ft of fencing will be needed \n" );
