Answer:
16 students can sit around a cluster of 7 square table.
Explanation:
Consider the provided statement.
It is required to find how many students can sit around a cluster of 7 square table.
The tables in a classroom have square tops.
Four students can comfortably sit at each table with ample working space.
If we put the tables together in cluster it will look as shown in figure.
From the pattern we can observe that:
Number of square table in each cluster Total number of students
1 4
2 6
3 8
4 10
5 12
6 14
7 16
Hence, 16 students can sit around a cluster of 7 square table.
Because 7 students can sit upper side, 7 students can sit lower side and 2 students can sit either ends(Left and right end). 7+7+2=16
