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, but still a 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 sq cm | 16 cm |
| 2) | 15 sq mm | 16 mm |
| 3) | 45 sq m | 28 m |
| 4) | 24 sq ft | 22 ft |
| 5) | 36 sq cm | 24 cm |
| 6) | 40 sq km | 26 km |

🔍 Explanation:
-
Area is the space inside the rectangle, measured in
square units.
-
Perimeter is the total distance around the outside, measured in
linear units.
- Always remember to use the correct units (cm², mm², m², etc.) for area and just cm, mm, m, etc. for perimeter.
