Let’s work through each rectangle one by one.
---
Problem 1:
The rectangle is made of small squares. Let’s count them.
- There are 5 columns and 4 rows.
- So, total squares = 5 × 4 = 20.
Each square is 1 cm × 1 cm → area = 1 square cm per square.
→ Area = 20 square cm.
✔ Check: 5 wide, 4 tall → 5×4=20. Correct.
---
Problem 2:
Count the grid squares.
- 3 columns, 4 rows → 3 × 4 = 12 squares.
→ Area = 12 square cm.
✔ Check: 3×4=12. Correct.
---
Problem 3:
Grid again.
- 6 columns, 3 rows → 6 × 3 = 18 squares.
→ Area = 18 square cm.
✔ Check: 6×3=18. Correct.
---
Problem 4:
Larger grid.
- 8 columns, 4 rows → 8 × 4 = 32 squares.
→ Area = 32 square cm.
✔ Check: 8×4=32. Correct.
---
Problem 5:
This one has labels: 5cm long, 3cm wide.
Area of rectangle = length × width
→ 5 × 3 = 15 square cm.
✔ Check: 5×3=15. Correct.
---
Problem 6:
It’s a square (all sides equal), 4cm on each side.
Area = side × side = 4 × 4 = 16 square cm.
✔ Check: 4×4=16. Correct.

Final Answer:
1) 20
2) 12
3) 18
4) 32
5) 15
6) 16
