Rules ↴

• The imperative sentence in Passive Voice begins with word “Let”.
• The word 'be' is used as an auxiliary verb in passive voice of imperative sentences.
• Base form is converted into past participle for making passive of imperative sentence.

Explanation ↴

As the sentence is in imperative form, 'let' will be used with it. The object will become the subject and the subject will become the object with 'be' attached before the past participle form of the main verb.
