## 最终结论
```python
def get_equal(tuples_list, length):
    for tup in tuples_list:
        if len(tup) != length:
            return 'All tuples do not have same length'
    return 'All tuples have same length'

# Test cases
assert get_equal([(11, 22, 33), (44, 55, 66)], 3) == 'All tuples have same length'
assert get_equal([(1, 2, 3), (4, 5, 6, 7)], 3) == 'All tuples do not have same length'
assert get_equal([(1, 2), (3, 4)], 2) == 'All tuples have same length'
```
