Calculating the Total Number of Trees Planted

To calculate the total number of trees planted, we can use the given information about the number of rows and the number of saplings in each row for birch and maple trees.

Let's start by calculating the total number of birch trees planted:

Birch Trees: - Number of rows for birch trees = 4 - Number of saplings per row for birch trees = 9

The total number of birch trees planted can be calculated by multiplying the number of rows by the number of saplings per row: Total birch trees = 4 rows * 9 saplings per row = 36 birch trees

Maple Trees: - Number of rows for maple trees = 3 - Number of saplings per row for maple trees = 8

Similarly, the total number of maple trees planted can be calculated by multiplying the number of rows by the number of saplings per row: Total maple trees = 3 rows * 8 saplings per row = 24 maple trees

Total Number of Trees Planted

To find the total number of trees planted, we can add the total number of birch trees and the total number of maple trees: Total trees planted = Total birch trees + Total maple trees Total trees planted = 36 birch trees + 24 maple trees = 60 trees

Therefore, a total of 60 trees were planted in the square according to the given conditions.
