Show Answer Key & Explanations Step-by-step solution for: Area of a Rectangle Worksheets - Math Monks
Let’s solve each rectangle area problem step by step.

Remember:
Area of a rectangle = length × width

We’ll multiply the two given sides for each rectangle. Don’t forget to include the correct unit squared (like cm², mm², etc.).

---

Problem 1:
Sides: 9 cm and 7 cm
Area = 9 × 7 = 63 cm²

---

Problem 2:
Sides: 4 mm and 8 mm
Area = 4 × 8 = 32 mm²

---

Problem 3:
Sides: 6 km and 3 km
Area = 6 × 3 = 18 km²

---

Problem 4:
Sides: 15 in and 5 in
Area = 15 × 5 = 75 in²

---

Problem 5:
Sides: 7 ft and 11 ft
Area = 7 × 11 = 77 ft²

---

Problem 6:
Sides: 5 yd and 9 yd
Area = 5 × 9 = 45 yd²

---

Problem 7:
Sides: 12 km and 6 km
Area = 12 × 6 = 72 km²

---

Problem 8:
Sides: 5 m and 6 m
Area = 5 × 6 = 30 m²

---

All calculations are simple multiplications — just make sure you’re multiplying the right numbers and writing the units correctly with a little “²” at the end!

Final Answer:
1. 63 cm²
2. 32 mm²
3. 18 km²
4. 75 in²
5. 77 ft²
6. 45 yd²
7. 72 km²
8. 30 m²
