To solve the problem of calculating the area of each shape by counting the squares, we need to count the number of individual squares in each grid. Each square represents 1 square unit (as indicated by the legend: "1 sq unit"). Let's go through each shape step by step:

---

Shape 1:

- The grid has 3 rows and 4 columns.
- Total squares = \( 3 \times 4 = 12 \).
- Area = 12 sq units.

---

Shape 2:

- The grid has 5 rows and 6 columns.
- Total squares = \( 5 \times 6 = 30 \).
- Area = 30 sq units.

---

Shape 3:

- The grid has 3 rows and 4 columns.
- Total squares = \( 3 \times 4 = 12 \).
- Area = 12 sq units.

---

Shape 4:

- The grid has 5 rows and 5 columns.
- Total squares = \( 5 \times 5 = 25 \).
- Area = 25 sq units.

---

Shape 5:

- The grid has 4 rows and 7 columns.
- Total squares = \( 4 \times 7 = 28 \).
- Area = 28 sq units.

---

Shape 6:

- The grid has 4 rows and 4 columns.
- Total squares = \( 4 \times 4 = 16 \).
- Area = 16 sq units.

---

Shape 7:

- The grid has 6 rows and 6 columns.
- Total squares = \( 6 \times 6 = 36 \).
- Area = 36 sq units.

---

Shape 8:

- The grid has 3 rows and 6 columns.
- Total squares = \( 3 \times 6 = 18 \).
- Area = 18 sq units.

---

Shape 9:

- The grid has 5 rows and 6 columns.
- Total squares = \( 5 \times 6 = 30 \).
- Area = 30 sq units.

---

Shape 10:

- The grid has 2 rows and 8 columns.
- Total squares = \( 2 \times 8 = 16 \).
- Area = 16 sq units.

---

Shape 11:

- The grid has 7 rows and 7 columns.
- Total squares = \( 7 \times 7 = 49 \).
- Area = 49 sq units.

---

Shape 12:

- The grid has 5 rows and 5 columns.
- Total squares = \( 5 \times 5 = 25 \).
- Area = 25 sq units.

---

Final Answers:

1. Area = 12 sq units
2. Area = 30 sq units
3. Area = 12 sq units
4. Area = 25 sq units
5. Area = 28 sq units
6. Area = 16 sq units
7. Area = 36 sq units
8. Area = 18 sq units
9. Area = 30 sq units
10. Area = 16 sq units
11. Area = 49 sq units
12. Area = 25 sq units
