Answer:
Area of figure = 42 square units
Step-by-step explanation:
You divide it into triangles and use 1/2 bh. Or better, you notice that you can use one enclosing rectangle and subtract four triangles. Much easier.
Area of rectangle diagonal (-5,-4) to (2,4) is 7×8 = 56 square units.
Area of outside triangle height 2 base 3 = 3 square units. There are two of them. The other is 4 square units.
Area of figure = 56 - 6 - 8 = 42 square units
