Let’s solve each rectangle one by one. We’ll use:

- Area = length × width
- Perimeter = 2 × (length + width)

We’ll check each calculation carefully.

1) Rectangle: 6 cm long, 2 cm wide

Area = 6 × 2 = 12 square cm
Perimeter = 2 × (6 + 2) = 2 × 8 = 16 cm

✔ Check: 6+2=8, times 2 is 16 — correct.

---

2) Rectangle: 5 mm long, 3 mm wide

Area = 5 × 3 = 15 square mm
Perimeter = 2 × (5 + 3) = 2 × 8 = 16 mm

✔ Check: 5+3=8, times 2 is 16 — correct.

---

3) Rectangle: 9 m tall, 5 m wide

Area = 9 × 5 = 45 square m
Perimeter = 2 × (9 + 5) = 2 × 14 = 28 m

✔ Check: 9+5=14, times 2 is 28 — correct.

---

4) Rectangle: 8 ft long, 3 ft wide

Area = 8 × 3 = 24 square ft
Perimeter = 2 × (8 + 3) = 2 × 11 = 22 ft

✔ Check: 8+3=11, times 2 is 22 — correct.

---

5) Square: 6 cm on each side

Area = 6 × 6 = 36 square cm
Perimeter = 2 × (6 + 6) = 2 × 12 = 24 cm
*(Or for a square: 4 × side = 4 × 6 = 24 cm — same answer)*

✔ Check: 6×6=36, and 4×6=24 — correct.

---

6) Rectangle: 8 km long, 5 km wide

Area = 8 × 5 = 40 square km
Perimeter = 2 × (8 + 5) = 2 × 13 = 26 km

✔ Check: 8+5=13, times 2 is 26 — correct.

---

Final Answer:
1) Area = 12 square cm, Perimeter = 16 cm
2) Area = 15 square mm, Perimeter = 16 mm
3) Area = 45 square m, Perimeter = 28 m
4) Area = 24 square ft, Perimeter = 22 ft
5) Area = 36 square cm, Perimeter = 24 cm
6) Area = 40 square km, Perimeter = 26 km
