Answer:

The missing side is 2, and the perimeter is 20

Explanation:

The formula for the area of a rectangle is length · width, so the first step is to replace all the known variables.

This makes the expression; length · 8 = 16.

Dividing by 8 makes it; length = 2.

the perimeters formula is 2 · (length + width).

Replacing these variables makes it; 2 · (2 + 8)

Simplifying this expression further makes it 2 · (10), which is 20.
