A little disconcertingly I generated the data of a triangle with integral sides in a spreadsheet. The area calculation suggested that it had zero area.
Knowing there was an obvious contradiction I wrote a computer listing to see if there were others which fitted this situation, and yes, there was an infinite number.
Clearly I am doing something wrong, explain.
(In reply to re: most likely way
Alternative explanation: You used calculus (integration) on the linear equations of the lines, and exactly half the area was below the x-axis and half above, and the "negative area" exactly balanced the "positive area" and so looked to be zero.
