You need to find the length of A F and BC first
Lets call BC --> 'x'
Lets form an equation
9 + 9 + x + x = 28
18 + 2x = 28
- 18
2x = 10
/ 2
x = 5
So now we have the length BC
We can subtract this length from the 11cm to find the vertical height of the trapezium
11 - 5 = 6
Now we have all we need to work it out.
area = (a + b) / 2 x h
area = (5 + 9) / 2 x 6
area = 42 cm^2
Have A Nice Day ❤

B should be correct
Hope that helped
Yes the x values are all different, if two were the same then it would not be one but in this case it is
$10.99 , divide 54.99 by 5 to get 10.99 for each shirt
Isolate x
So xy - 2 = k
Then
xy = k + 2
x = (k+2)/y
