12 units squared
Step-by-step explanation:
You realize that the shape can be divided into 3 shapes;
2 right-angled triangles (one small and one bigger one) and a rectangle. We can find the area of each and then sum them up. Because we are finding area under the shape, the negative signs will be ignored;
Larger right-angled triangle;
½ b * h
½ * 4 * 4 = 8
Smaller right-angled Triangle;
½ * b * h
½ * 2 * 2 = 2
Rectangle;
L * W
2 * 1 = 2
Sum of all the areas;
2 + 2 + 8 = 12
= 12 units squared
