Hi Brahma,
  
trigger ContactTrigger on Account(before delete) {
    List < Account > accList = new List < Account > ();
    Set < id > accIdSet = new Set < id > ();
    for (Account acc: Trigger.old) {
        accIdSet.add(acc.id);
    }

    Map < Id, Account > accts = new Map < Id, Account > ([Select Id, (Select Id from contacts) from Account where id in: accIdSet]);

    for (Account acc: Trigger.old) {
        if (accts.get(acc.id).contacts.size() > 0) {
            acc.adderror('Account cannot be deleted');
        }
    }

}

Thanks, 
Bhanu Prakash
