Can a Child contract change values of a parent contract in Solidity

If we have 2 contracts like so :

contract A {
  struct SampleA{
    uint id;
    bytes32 name;
    bytes32 toChange;
  }
  mapping (uint=> SampleA) public idToStruct;
}

contract B is A{
  function changeVar (bytes32 newVar) public {
    idToStruct[0].toChange = newVar;
  }
}

Can I update variable in Contract A from contract B like this? Is this possible in solidity, if not is there a workaround?

Yes, you can modify properties of the parent contract, as long as the property is not private.
