Answer:
6 square units
Step-by-step explanation:
Given shape is of a trapezoid:
![area \: of \: trapezoid \\ = \frac{1}{2} \times (4 + 2) \times 2 \\ \\ = 6 \: {units}^{2}](https://tex.z-dn.net/?f=area%20%5C%3A%20of%20%5C%3A%20trapezoid%20%20%5C%5C%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%20%284%20%2B%202%29%20%5Ctimes%202%20%5C%5C%20%20%5C%5C%20%20%3D%206%20%5C%3A%20%20%7Bunits%7D%5E%7B2%7D%20)
Area of shape = area of square + area of triangle
![= 2^2 + \frac{1}{2} \times 2\times 2\\= 4 + 2\\= 6\: units^2 \\](https://tex.z-dn.net/?f=%20%3D%202%5E2%20%2B%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%202%5Ctimes%202%5C%5C%3C%2Fp%3E%3Cp%3E%3D%204%20%2B%202%5C%5C%3C%2Fp%3E%3Cp%3E%3D%206%5C%3A%20units%5E2%20%5C%5C)
