I'm not really sure what your question is, but here are some tips. A formal letter uses formal language, so be sure to make the tone of your letter sound professional. Refer to the chairman with their title, ex. Chairman Bob. Identify yourself in the first sentence of the letter, ex. I am Bob from Monacan High School and I am a senior wanting change in "blank" area. Be clear in what the problem is you want ammended, and propose some solutions to the problem, do not just give the chairman problems to think about. Use perfect syntax and grammar, the more professional you sound, the more likely the chairman will pay attention to your letter. End the letter with Best Regards, or just regards.
