To find the missing side of a rectangle when given the perimeter, we can use the formula for the perimeter of a rectangle:

\[
P = 2(length + width)
\]

Given that the perimeter \(P\) is 42 cm, we can set up the equation:

\[
42 = 2(length + width)
\]

We can simplify this equation by dividing both sides by 2:

\[
21 = length + width
\]

If you have one of the sides (either the length or the width), you can substitute it into this equation to find the missing side. For example, if the length is known to be \(x\), then the width would be:

\[
width = 21 - x
\]

However, without specific values for either the length or width, the exact missing side cannot be determined. If you provide the value of one side, I can help you find the other side.
