You did nothing wrong . . . leep going!

Find the area of the triangle with vertices (0,-3), (4,-4) and (-2,6)

So for this one i found 2 vectors: . . . . . Right!

took the cross product of the two to get: . . . . . Yes!

Where am i going wrong?

Recall that themagnitudeof the cross product gives the area of the parallelogram.

Area of parallelogram: .

Therefore, area of triangle: .
