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:  .
.
>Thus,
Area = 
 
        
                    
             
        
        
        
First you would find that not all the units are the same in this problem, so you convert yards to feet. So 4 yards = 12 feet. 
The proportion you would make would be x/12 = 2/1
