can some one also please help my one that i should do after i finds the area of the square aka how to find the area of the triangle.

Answer:
6 square units
Step-by-step explanation:
Given shape is of a trapezoid:
[tex]area \: of \: trapezoid \\ = \frac{1}{2} \times (4 + 2) \times 2 \\ \\ = 6 \: {units}^{2} [/tex]
Area of shape = area of square + area of triangle
[tex] = 2^2 + \frac{1}{2} \times 2\times 2\\
= 4 + 2\\
= 6\: units^2 \\[/tex]
