Let’s go through each problem step by step.
We are looking at rectangular grids (arrays) made of squares.
Each grid has
rows (horizontal lines of squares) and
columns (vertical lines of squares).
Then we write a repeated addition equation: add the number of squares in each row, as many times as there are rows.

Example given:
- 3 rows, 6 columns → 6 + 6 + 6 = 18
(That means 3 groups of 6)

Now let’s do each one:
---
Problem 1:
Grid: 3 rows, 4 columns
→ 4 + 4 + 4 = 12
Answer: 3 rows, 4 columns → 4+4+4=12
---

→ 6 + 6 + 6 + 6 = 24
Answer: 4 rows, 6 columns → 6+6+6+6=24
---
Problem 8:
Grid: 5 rows, 4 columns
→ 4 + 4 + 4 + 4 + 4 = 20
Answer: 5 rows, 4 columns → 4+4+4+4+4=20
---
Problem 9:
Grid: 4 rows, 4 columns
→ 4 + 4 + 4 + 4 = 16
Answer: 4 rows, 4 columns → 4+4+4+4=16
---
Problem 10:
Grid: 3 rows, 7 columns
→ 7 + 7 + 7 = 21
Answer: 3 rows, 7 columns → 7+7+7=21
---
Problem 11:
Grid: 5 rows, 5 columns
→ 5 + 5 + 5 + 5 + 5 = 25
Answer: 5 rows, 5 columns → 5+5+5+5+5=25
---
Final Answer:
1. 3 rows, 4 columns → 4+4+4=12
2. 4 rows, 4 columns → 4+4+4+4=16
3. 3 rows, 5 columns → 5+5+5=15
4. 3 rows, 6 columns → 6+6+6=18
5. 4 rows, 3 columns → 3+3+3+3=12
6. 3 rows, 5 columns → 5+5+5=15
7. 4 rows, 6 columns → 6+6+6+6=24
8. 5 rows, 4 columns → 4+4+4+4+4=20
9. 4 rows, 4 columns → 4+4+4+4=16
10. 3 rows, 7 columns → 7+7+7=21
11. 5 rows, 5 columns → 5+5+5+5+5=25
