Not able to Restore Bootcamp partition

Hi,

i am using bootcamp for a while. Both mac and windows got slower. so i decided to remove the bootcamp. i used the bootcamp assistant to delete bootcamp drive and to restore the space with MAC. i got the error from bootcamp assistant "Your disk couldn't be restored" and from the next time restore / remove option not there in BC assistant. Even through disk utility i am not getting the space. Please help me, As per other threads i am posting few commands output.
