Area and Perimeter of Rectangles 2 - Math worksheet with six rectangle problems for calculating area and perimeter using different units.

Let's solve each rectangle step by step using the formulas:

Formulas:

- Area of a rectangle = length × width
- Perimeter of a rectangle = 2 × (length + width)

---

1) Rectangle: 6 cm × 2 cm

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

✔ Area = 12, Perimeter = 16

---

2) Rectangle: 5 mm × 3 mm

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

✔ Area = 15, Perimeter = 16

---

3) Rectangle: 5 m × 9 m

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

✔ Area = 45, Perimeter = 28

---

4) Rectangle: 8 ft × 3 ft

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

✔ Area = 24, Perimeter = 22

---

5) Square: 6 cm × 6 cm (It's a square, which is a special rectangle)

- Area = 6 cm × 6 cm = 36 square cm
- Perimeter = 2 × (6 + 6) = 2 × 12 = 24 cm

✔ Area = 36, Perimeter = 24

---

6) Rectangle: 8 km × 5 km

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

✔ Area = 40, Perimeter = 26

---

✔ Final Answers:

| Problem | Area | Perimeter |
|--------|--------------------|-------------------|
| 1) | 12 square cm | 16 cm |
| 2) | 15 square mm | 16 mm |
| 3) | 45 square m | 28 m |
| 4) | 24 square ft | 22 ft |
| 5) | 36 square cm | 24 cm |
| 6) | 40 square km | 26 km |

📌 Key Tips:

- Always check units! (cm, mm, m, ft, km)
- Area is always in square units (cm², mm², etc.)
- Perimeter is in linear units (cm, mm, etc.)
- Remember: Area = inside, Perimeter = outside
