Hi Sia,

You can follow the below steps:
  1. Create a trigger on Task object. Context would be after update
  2. If the status is changed to Completed, store the related account id in a set.
  3. Query the account records along with the child tasks where status is equal to Completed.
  4. Now set the custom field = related tasks size.
  5. Update the account.
Let me know if you need any help with the trigger code.
