Question

Peter said I worked in the garden yesterday to reported speech​

Answer 1

Question:

Peter said, " I worked in the garden yesterday."

Answer:

Peter said that he had worked in the garden the previous day.

Explanation:

=> "Worked" is in the past tense, this becomes past perfect, "had worked".

=> "I" is replaced with "he" as we are conveying this in third person.

=> "Yesterday" in reported speech becomes "the previous day"/ "the day before" as this speech is to be reported.

=> Lastly, we add "that" in the reported speech.
