Answer: 230cm²

Step-by-step explanation:

>We can do this by splitting the figure into 2 trapeziums.

>Additionally, you can see that both trapeziums bear the same lengths a and b. Hence, we can use this formula: $\frac{1}{2} * (a+b) * (total height)$ .

>Thus,

Area = $\frac{1}{2} *(7+16)*20=230$
