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.

How to draw every type of triangle?
I was only able to generate a equilateral triangle with my code below;
sides = 3;
t = (1/(2*sides):1/(sides):1)*2*pi-pi/3;
b = User_input(3);
x = b*sin(t)+5/8*xmax;
y = b*cos(t)+3/4*ymax;

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.
