Hello, I have another question from my linear algebra class. I'm asked to find the area of a triangle using determinants, but they don't give me the vertices, only the sides. Where A,B,C and D are the vertices, u and v are 2 out of the 3 sides. Now they give me u=(-3,1) and v=(0,2). My question is, can I still use the formula 0.5[x2-x1 + y2-y1] even if the coordinates I have are not those of the vertices?

Thank you
