The attempted solution looks correct. What's the problem?
 
I am not entirely sure i was just given feedback which said. Ensure that you are using the correct values in calculations
 
Yeah. You calculated the areas for some of the stresses incorrectly.
 
Could you tell me which axis where the area is incorrect
