document.write( "As you can see looking on coordinates of the points P and Q, the side PQ is horizontal and has the length of -2 - (-9) = 7 units.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, the perimeter of the equilateral triangle PQR is 3 times this value, i.e. 21 units.\r\n" );
