a restaursnt has rectangular tables that can seat 8 people each when there are more than 8 people in a group the tables are moved together. what is the greatest number of people who can sit at 3 tables lined up in a row?
Each table is 3 seats long and 1 seat wide. If you push 3 tables together, end to end, they become 9 seats long, and remains 1 seat wide. If you add up the perimeter, it comes out to 9+9+3+3, which is 24.
