A meterstick broke into two pieces if one piece was 54 cm long how was the other piece?

If the meterstick was broken into 2 perfect halves, then the answer would be 50cm.

If the whole stick was 54cm, and it was broken into 2 pieces, then the answer would be 27cm.

The question refers to breaking the rule into uneven parts, one at 54cm, so then the other part is 100-54 = 46cm.
