document.write( "The height of a triangle is 6 m more than twice the length of the base.
\n" );
document.write( "The area of the triangle is 28 m^2 = L*H
\n" );
document.write( "  x(2x+6) =28
\n" );
document.write( "  2x^2 + 6x -28 = 0
\n" );
document.write( "   x^2 + 3x -14 = 0
\n" );
document.write( " 
\n" );
document.write( "   = (-3 +8.06)/2 = 2.5 rounded to 1 decimal point (throwing out neg solution for unit measure
\n" );
document.write( "length = 2.5m, height is 11m \n" );
