Explanation:
No trapezoid is attached; so, I will solve on a general note
The area of a trapezoid is:
![Area = (1)/(2)(Sum\ of\ parallel\ sides) * Height](https://img.qammunity.org/2022/formulas/mathematics/college/bgn5de4w0k9awhfp6u2ovsll0zmtgjd3n6.png)
Using the attached image as a point of reference;
The parallel sides are: AD (6cm) and BD (12cm)
The height is 4cm
So, the area is:
![Area = (1)/(2) * (6cm + 12cm) * 4cm](https://img.qammunity.org/2022/formulas/mathematics/high-school/ogb8tprw9w26lx5x6bqhgqjiam8yc3c8qj.png)
![Area = 18cm * 2cm](https://img.qammunity.org/2022/formulas/mathematics/high-school/mgjezojdii6yc7a1qe0qfkgo0myp94nxs7.png)
![Area = 36cm^2](https://img.qammunity.org/2022/formulas/mathematics/high-school/a4xhms59qolpymdhx5vfxkyyog0pqhjgbm.png)
