To calculate the perimeters of the squares, we can use the formula for the perimeter of a square, which is:
\[ P = 4 \times \text{side length} \]
For the smaller square:
- Side length = 3 cm
- Perimeter = \( 4 \times 3 = 12 \) cm
For the larger square:
- Side length = 24 cm
- Perimeter = \( 4 \times 24 = 96 \) cm
Now, we can find the ratio of the perimeters of the smaller square to the larger square:
\[ \text{Ratio} = \frac{\text{Perimeter of smaller square}}{\text{Perimeter of larger square}} = \frac{12}{96} = \frac{1}{8} \]
So, the final answer is:
1/8
