This is my code below :

Use sprintf() to create a string with the area in it. Then use text() to place it in the axes
caption = sprintf('Area = %.1f', area);
text(x, y, caption);
Of course you need to figure out what x and y are to position the string in the best looking spot.

Not sure what you mean. To get every triangle, or just any triangle in general, you have to make the x and y have the coordinates of the three vertices. But I'm sure you know that already , so I'm not really sure what the question is.
