(8+9)*10=170

Answer 3

Solution 1: Using Arithmetic

To find the total number of saplings planted, we can use the information provided about the number of rows of apple and pear trees.

Number of Rows of Apple Trees: 9 rows Number of Rows of Pear Trees: 8 rows

To find the total number of saplings planted, we can use the formula: Total saplings = (Number of rows of apple trees * Number of saplings per row) + (Number of rows of pear trees * Number of saplings per row)

Plugging in the given values: Total saplings = (9 * 10) + (8 * 10)

Total saplings = 90 + 80 Total saplings = 170

So, a total of 170 saplings were planted in the garden.

Solution 2: Using Multiplication

Another way to solve this problem is by multiplying the number of rows by the number of saplings per row for each type of tree and then adding the results together.

Number of Rows of Apple Trees: 9 rows Number of Rows of Pear Trees: 8 rows Number of Saplings per Row: 10 saplings

Using multiplication: Total saplings = (Number of rows of apple trees * Number of saplings per row) + (Number of rows of pear trees * Number of saplings per row)

Plugging in the given values: Total saplings = (9 * 10) + (8 * 10)

Total saplings = 90 + 80 Total saplings = 170

So, a total of 170 saplings were planted in the garden using this method as well.
