This is a compound figure
First, section off a triangle at bcd. The base is 8 units with a height of 2 units so the area is 8 square units.
Form a trapezoid between the areas where x is -3 to 1. Use the formula to find the area (28 square units).
There are two triangles left. Find the area of both of them (4 units and 2 units)
Add all of these values together to get a total of 42 square units
