Answer: Unknown
Explanation:
Well, we know that Mr. Seipel's homeroom is 11/10 times the width of Miss Rivas' homeroom. Because 11/10 = 1.1, we can multiply Miss Rivas' homeroom width by 1.1 to get Mr. Seipel's homeroom width. We can also divide Mr. Seipel's homeroom width by 1.1 to get Miss Rivas' homeroom width. But, you didn't provide the question in your post.
