Explanation:

Step1: Recall rectangle perimeter formula

The perimeter $P$ of a rectangle is given by $P = 2(\text{length} + \text{width})$.

Step2: Substitute given values

Let $x$ = width, length = 20.8, $P$ = 78.6. Substitute into the formula:
$$78.6 = 2(20.8 + x)$$

Answer:

$78.6 = 2(20.8 + x)$
