Answer:

14.4

Explanation:

We can break this quadrilateral into 2 triangles, one with a height of 3.2, and one with a height of 4.

Area of the first triangle = 1/2*(2+2)*3.2 = 6.4. This is because the base is 2+2, and the height is 3.2.

Second triangle = 1/2*(2+2)*4 = 8.

Whole thing: 6.4 + 8 = 14.4 sq. units
