My teacher says I have 10 trees and 5 rows I want 4 trees in each row?

Don't limit your thinking just to a rectangular pattern.

50/4 = 12.5

Two of the trees need to be in two different rows.

arrange the 10 trees in a pentagram. Each of the five diagonals has 4 trees.

To find out if you can have 4 trees in each row, you need to determine if you have enough trees to evenly distribute them across the rows. Here's how you can do it:

1. Calculate the total number of trees you have: 10 trees

2. Calculate the total number of rows: 5 rows

3. Determine the maximum number of trees you can have in each row by dividing the total number of trees by the total number of rows: 10 trees ÷ 5 rows = 2 trees per row

Since the maximum number of trees you can have in each row is 2, you cannot have 4 trees in each row.
