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?
+36916 Here is ONE way .....calculate the area of the red rectangle ...then subtract the 4 triangles
5 x4 - 2 * 1/2 (1 * 3) - 2 * 1/2 (4 * 1) = 20 - 3 - 4 = 13 units 2 as TA posted !
+373 Hey there, Guest!
The answer is 13 units squared.
You have to count and then do some division.
Hope this helped! :)
