Consider a triangle with vertices at (0,0) and (x1, 71) and (x2, 92). a. use the interpretation of a determinant as area of a parallelogram to explain why the following formula calculates the area of the triangle. (hint: a diagonal of a parallelogram cuts the parallelogram into two triangles of equal size a =\det (i 2) b. set (x1, y.) = (1,2) and (x2,y2) = (3,-1). use the formula to calculate the area of the triangle.
