|x1 x2|

|y1 y2| and if the parallelogram is above the x axis, then the area is positive else its negative...so the determinants I have tried,

|-2 6|

|-2 4| and det = 4 but if I use the other two points I get a different answer

|0 4|

|3 -1| and det = 12 but once I draw the parallelogram I found the area to be 6x5=30...what am I doing wrong?

You've drawn the parallelogram. So can you see the vectors which determine that parallelogram?
