▲ ▲ ▲ ▲ ▲ ▲
```
- There are
4 rows.
- Each row has
6 triangles.
- So, the multiplication sentence is:
4 × 6 = 24
✔ Correct!

□ □ □ □ □ □ □ □ □ □ □ □
```
- Count the
rows: 5 rows
- Count the
columns (number of squares in one row): 12 squares per row
So, the multiplication sentence is:
5 × 12 = 60

Problem 3:
```
○ ○ ○ ○
○ ○ ○ ○
○ ○ ○ ○
○ ○ ○ ○
○ ○ ○ ○
```
- Rows: 5
- Columns: 4
So, the multiplication sentence is:
5 × 4 = 20

```
- Rows: 6
- Columns: 15
So, the multiplication sentence is:
6 × 15 = 90

✔ Final Answers:
| Array | Multiplication Sentence |
|-------|-------------------------|
| 1. | 4 × 6 = 24 |
| 2. |
5 × 12 = 60 |
| 3. |
5 × 4 = 20 |
| 4. |
6 × 15 = 90 |
| 5. |
8 × 15 = 120 |

🔍 Explanation:
In each case:
- The
number of rows becomes the
first factor.
- The
number of items in each row (columns) becomes the
second factor.
- Multiply them to get the total number of items.
