Let’s solve each rectangle one by one. We’ll use:
-
Area = Length × Width
-
Perimeter = 2 × (Length + Width)
We’ll go step by step for all 6 rectangles.
---
Rectangle 1:
- Length = 5 cm, Width = 4 cm
- Area = 5 × 4 =
20 cm²
- Perimeter = 2 × (5 + 4) = 2 × 9 =
18 cm
---
Rectangle 2:
- Length = 3 cm, Width = 4 cm
- Area = 3 × 4 =
12 cm²
- Perimeter = 2 × (3 + 4) = 2 × 7 =
14 cm
---
Rectangle 3:
- Length = 5 cm, Width = 2 cm
- Area = 5 × 2 =
10 cm²
- Perimeter = 2 × (5 + 2) = 2 × 7 =
14 cm
---
Rectangle 4:
- Length = 4 cm, Width = 2 cm
- Area = 4 × 2 =
8 cm²
- Perimeter = 2 × (4 + 2) = 2 × 6 =
12 cm
---
Rectangle 5:
- Length = 4 cm, Width = 4 cm → This is a square!
- Area = 4 × 4 =
16 cm²
- Perimeter = 2 × (4 + 4) = 2 × 8 =
16 cm
---
Rectangle 6:
- Length = 5 cm, Width = 1 cm
- Area = 5 × 1 =
5 cm²
- Perimeter = 2 × (5 + 1) = 2 × 6 =
12 cm
---
Final Answer:
1. Area = 20 cm², Perimeter = 18 cm
2. Area = 12 cm², Perimeter = 14 cm
3. Area = 10 cm², Perimeter = 14 cm
4. Area = 8 cm², Perimeter = 12 cm
5. Area = 16 cm², Perimeter = 16 cm
6. Area = 5 cm², Perimeter = 12 cm
