I believe its d because that was what I was doing 2days ago
First step is to plot all the given coordinates in the xy plane.
Notice that after plotting the points A, B, C and D, we have got the figure ABCD is a trapezium with bases AD = 4 units, BC = 6 units and height: DE= 5 units.
Formula to find the area of trapezium is:
Area = 
= 
=
= 5 * 5
= 25 square units.
So, third choice is correct.
Hope this helps you!
No because when you add any 2 sides the answer has to be bigger than the 3rd side
ex: 2+7=9
9 is too small, so the tips of the side that is 2ft would not touch the side that is 7ft
