12∣x1y2−x2y1∣\frac{1}{2}|x_1y_2 - x_2y_1|21∣x1y2−x2y1∣
When one vertex is at origin (0,0)
To ensure area is always positive
Multiply x1x_1x1 by y2y_2y2 and x2x_2x2 by y1y_1y1
When no vertex is at the origin
No, area stays the same
5.5 square units
Subtract 2 from x's, 4 from y's
Multiply by 12\frac{1}{2}21
Forgetting absolute value
Area is double the correct value
Yes, result will be the same
