Problem Analysis

To find the total number of trees planted in the park, we need to calculate the sum of the trees in each row for both the rows of spruce trees and the rows of birch trees.

Solution

Let's calculate the number of trees in each row for the spruce trees and the birch trees separately.

For the spruce trees: - There are 3 rows of spruce trees. - Each row has 23 trees.

So, the total number of spruce trees is 3 rows * 23 trees/row = 69 trees.

For the birch trees: - There are 2 rows of birch trees. - Each row has 14 trees.

So, the total number of birch trees is 2 rows * 14 trees/row = 28 trees.

To find the total number of trees in the park, we add the number of spruce trees and the number of birch trees:

Total number of trees = Number of spruce trees + Number of birch trees = 69 trees + 28 trees = 97 trees.

Therefore, a total of 97 trees were planted in the park.

Answer

The total number of trees planted in the park is 97 trees.
