I'll solve each problem step by step, calculating the area and perimeter for each shape.
Problem 1: Rectangle with length 8m and width 5m
- Area = length × width = 8 × 5 = 40 m²
- Perimeter = 2(length + width) = 2(8 + 5) = 2(13) = 26 m
Problem 2: Square with side 6m
- Area = side × side = 6 × 6 = 36 m²
- Perimeter = 4 × side = 4 × 6 = 24 m
Problem 3: Rectangle with length 12m and width 3m
- Area = length × width = 12 × 3 = 36 m²
- Perimeter = 2(length + width) = 2(12 + 3) = 2(15) = 30 m
Problem 4: Rectangle with length 7m and width 6m
- Area = length × width = 7 × 6 = 42 m²
- Perimeter = 2(length + width) = 2(7 + 6) = 2(13) = 26 m
Problem 5: Rectangle with length 9m and width 6m
- Area = length × width = 9 × 6 = 54 m²
- Perimeter = 2(length + width) = 2(9 + 6) = 2(15) = 30 m
Problem 6: Rectangle with length 15m and width 5m
- Area = length × width = 15 × 5 = 75 m²
- Perimeter = 2(length + width) = 2(15 + 5) = 2(20) = 40 m
Problem 7: Rectangle with length 8m and width 7m
- Area = length × width = 8 × 7 = 56 m²
- Perimeter = 2(length + width) = 2(8 + 7) = 2(15) = 30 m
Problem 8: Square with side 9m
- Area = side × side = 9 × 9 = 81 m²
- Perimeter = 4 × side = 4 × 9 = 36 m
Final Answer:
1. Area = 40 m², Perimeter = 26 m
2. Area = 36 m², Perimeter = 24 m
3. Area = 36 m², Perimeter = 30 m
4. Area = 42 m², Perimeter = 26 m
5. Area = 54 m², Perimeter = 30 m
6. Area = 75 m², Perimeter = 40 m
7. Area = 56 m², Perimeter = 30 m
8. Area = 81 m², Perimeter = 36 m
Parent Tip: Review the logic above to help your child master the concept of area and perimeter worksheets.
