In the diagram, the four points have coordinates A(0,1), B(1,4), C(5,3), and D(4,0). What is the area of quadrilateral ABCD?
You can find the length of the sides sing the distance formula:
(x2, y2) is a coordinate point
(x1, y1) is a coordinate point
Once you find the two points you are going to use, plug them in into the distance formula and solve for the distance
Then, find the area
