The formula for the perimeter \( P \) of a rectangle is given by:
\[
P = 2 \times (\text{length} + \text{width})
\]
For a rectangle with a length of 4.5 cm and a width of 8.2 cm, we can substitute the values into the formula:
\[
P = 2 \times (4.5 \, \text{cm} + 8.2 \, \text{cm})
\]
Calculating the sum inside the parentheses:
\[
4.5 \, \text{cm} + 8.2 \, \text{cm} = 12.7 \, \text{cm}
\]
Now, substituting back into the perimeter formula:
\[
P = 2 \times 12.7 \, \text{cm} = 25.4 \, \text{cm}
\]
Thus, the perimeter of the rectangle is \( \boxed{25.4} \) cm.
