Cambridge Dictionary always disappoints me. In the entry of "worth", it is said that it is an "adjective":
[https://dictionary.cambridge.org/dictionary/english-chinese-simplified/worth][1]
e.g. Our house is worth £200,000.
In fact, Longman is correct in regarding it as a preposition:

e.g. The company’s assets are worth $70 a share.
Am I right?
