To find the perimeter of a rectangle, you use the formula:

[tex]\[ \text{Perimeter} = 2 \times (\text{length} + \text{breadth}) \][/tex]

Given:
- Length \( = 12 \, \text{cm} \)
- Breadth \( = 7 \, \text{cm} \)

Step-by-step solution:

1. Identify the length and breadth:
- Length \( l \) is \( 12 \) cm.
- Breadth \( b \) is \( 7 \) cm.

2. Add the length and breadth:
[tex]\[ l + b = 12 \, \text{cm} + 7 \, \text{cm} = 19 \, \text{cm} \][/tex]

3. Multiply the sum by 2 to find the perimeter:
[tex]\[ \text{Perimeter} = 2 \times 19 \, \text{cm} = 38 \, \text{cm} \][/tex]

Therefore, the perimeter of the rectangle is [tex]\( 38 \)[/tex] cm.
