Let's solve the problem step by step.
We are asked to
work out the perimeter of each rectangle. The
perimeter of a rectangle is calculated using the formula:
$$
\text{Perimeter} = 2 \times (\text{length} + \text{width})
$$
We'll go through each rectangle one by one.
---
1. Rectangle with length 3 cm and width 2 cm
$$
\text{Perimeter} = 2 \times (3 + 2) = 2 \times 5 = 10\,\text{cm}
$$
---
2. Rectangle with length 6 cm and width 8 cm
$$
\text{Perimeter} = 2 \times (6 + 8) = 2 \times 14 = 28\,\text{cm}
$$
---
3. Rectangle with length 4 cm and width 6 cm
$$
\text{Perimeter} = 2 \times (4 + 6) = 2 \times 10 = 20\,\text{cm}
$$
---
4. Rectangle with length 5 cm and width 4 cm
$$
\text{Perimeter} = 2 \times (5 + 4) = 2 \times 9 = 18\,\text{cm}
$$
---
5. Rectangle with length 1 cm and width 4 cm
$$
\text{Perimeter} = 2 \times (1 + 4) = 2 \times 5 = 10\,\text{cm}
$$
---
6. Rectangle with length 8 cm and width 5 cm
$$
\text{Perimeter} = 2 \times (8 + 5) = 2 \times 13 = 26\,\text{cm}
$$
---
7. Rectangle with length 2 cm and width 4 cm
$$
\text{Perimeter} = 2 \times (2 + 4) = 2 \times 6 = 12\,\text{cm}
$$
