Answer:
The equation will be:

Explanation:
Side lengths
⇒ 4.5 8.5 10.25 13.75
Perimeter
⇒ 18 34 41 55
First we will pick any two ordered pairs in form of point like
. So, here
and

Now, the slope will be:

So, the equation using the point-slope form will be..............

Thus, the equation that represents the relationship between the side length
and the perimeter
will be:
