Question

active passive a)i shall have planted a tree

Answer 1

A tree shall have been planted by me

Answer 2

Given sentence :-

I shall have planted a tree.


Given sentence is in future perfect tense active voice. Rule for active voice of future perfect tense is :-

Sub + will/shall + have + verb 3rd + obj

Its passive form becomes

Obj + will/shall + have + been + verb 3rd + by + sub

Here, sub = I

Object = a tree

Verb 3rd = Planted.

While converting to passive,

=> Subject of active voice becomes the object of passive voice and vice versa.

=> By is used before the obj of passive voice.

=> Verb is always in 3rd form.


Hence, your answer is :-

A tree shall have been planted by me.
