A quadrilateral has four points A(0,1), B(1,3), C(5,2) and D(4,0) as coordinates, how do I find the area?
I suggest graphing this to visualize it better. Once you graph it, you can see that it is a parallelogram. You can easily find the area by drawing a rectangular figure around the shape and subtracting small triangles
