Agroup of 225 student needs to be arranged in a square formation for a halftime performance showhow many students should be lined up in each row?

15 students should be lined up in each row.

Step-by-step explanation:

A group of 225 student needs to be arranged in a square formation.

This means same number of students will sit in each row as in each column.

To find this we will take the square root of 225.

There will be = students in each rows and columns.

Therefore, 15 students should be lined up in each row.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
