3. = 6/12 
6. = 4/6
9. = 8/12
12. = 9/12
15. = 9/9
18. = 4/6 
Hope this helps !
        
                    
             
        
        
        
We are given a trapezoid TRHY.
Height of the trapezoid = 13 units.
b1 = 21 units and 
Area = 215 units squares.
We need to find the length of b2.
We know formula for area of a trapezoid.

Plugging values in formula.
215 =  (21+b2)× 13.
(21+b2)× 13.
215 = 6.5(21+b2)
Dividing both sides by 6.5, we get 

33.08 = 21+b2.
Subtracting 21 from both sides, we get 
33.08-21 = 21-21+b2
b2 = 12.08.
<h3>Therefore,  length of b2 is 12.08 units.</h3>
 
        
             
        
        
        
Answer:
x ≈ 21.7
I rounded to the nearest tenth because the values are given in tenths. The first few digits of x are below if you are rounding to something else, as the image is cut out.
