Answer 3

Calculating the Number of Birch Trees

To calculate the total number of birch trees on the alley, we can use the information provided.

Given: - Initially, there were 40 birch trees. - 3 additional rows were planted, with 10 trees in each row.

Calculation

To find the total number of birch trees after planting the additional rows, we can use the following calculation:

Total birch trees = Initial birch trees + (Number of additional rows * Trees in each row)

Total birch trees = 40 + (3 * 10)

Total birch trees = 40 + 30

Total birch trees = 70

So, after planting the additional rows, there are 70 birch trees on the alley.
