Hello There!!~ (●'◡'●)
The answer to this is: 1/2 From what you have here, it looks like h is given as sqrt(2) and that base length b must be determined from the points given. The area of a triangle being simply (base length * height from base)/2 or:
area = 1/2 * b * h
_|_|_|_|_|_|_|A|_|_|_|_| 4
_|_|_|_|_|_|_|_|_|_|_|_| 3
_|_|_|_|_|_|_|_|_|_|_|_| 2
_|_|_|_|_|_|_|_|_|_|_|_| 1
_|_|_|_|_|_|_|_|_|_|_|_| 0
_|_|_|_|B|_|_|_|_|_|_|_| -1
_|_|_|C|_|_|_|_|_|_|_|_| -2
-5 -4 -3 -2 -1 0 1 2 3 4 5
After plotting the points, and knowing that the triangle BCD where D is (-2,-2) gives each base as 1 unit and the hypotenuse as sqrt(2), The height from a base should be perpendicular to that base, so b looks like sqrt(2) and h = sqrt(2), so solve for your area with the 1/2 b*h.
Hope It Helped!~
And, Tell me if The answer is wrong...
Good Luck With Your Assignment!~
