Final answer:
A properly assembled business letter includes, in order: Heading, Inside address, Greeting, Body, Closing, and Signature, with block formatting being the most common and preferred layout.
Step-by-step explanation:
To correctly assemble the parts of a business letter, one must follow the conventional order which typically adheres to a standard format. Here is how you should organize the parts:
- Heading: This includes your return address and the date.
- Inside address: The recipient's address, including the name of the person, title, and organization address.
- Greeting: A polite salutation using the recipient's title and last name.
- Body: The main content of your letter, explaining the purpose and providing details.
- Closing: A formal closing phrase, such as 'Sincerely'.
- Signature: Your signature above your typed name.
Remember, block formatting is the most common way to format a business letter. Everything should be left-justified, with single spacing within paragraphs and double spacing between them. Avoid indentations at the beginning of paragraphs. Lastly, ensure a clear subject line and maintain a formal but concise tone throughout the letter.
