A quadrilateral has four points A(0,1), B(1,-3), C(5,-2) and D(4,0) as coordinates What is the area of quadrilateral ABCD?
+2668 We can enclose the shape in a \(5 \times 4 \) grid. From here, we can subtract the areas of the regions that do not lie in the shaded shape (see graph below)
Doing so, we find the area is \(20 - 2 - 2 - 2 - 1 - 1 = \color{brown}\boxed{12}\)
Here is the graph:
