To find the perimeter of a rectangle, you can use the formula:
\[ \text{Perimeter} = 2 \times (\text{Length} + \text{Width}) \]
In this case, the length is 4.5 cm and the width is 9.5 cm. Substituting in the values:
\[ \text{Perimeter} = 2 \times (4.5 , \text{cm} + 9.5 , \text{cm}) = 2 \times (14 , \text{cm}) = 28 , \text{cm} \]
The answer is A. 28 cm.
