Answer:
The perimeter is the sum of the length of the sides of a certain shape. In this case, the perimeter of the polygon would be the sum of the lengths of sides AB, BC, CD, and DA.
Step-by-step explanation:
Lets start computing the length of each side of the polygon. Using points A and B as a first example, we find that the distance between them will be:

Where
and
are the coordinates of points A and B respectively.
From the graph we can see that point A has coordinates (5, 12), B has coordinates (9, 9), C has coordinates (12, 5), and D has coordinates (0, 0). Puting values and computing the lengths we find that:
<em>Lenght AB:</em>



<em>Lenght BC:</em>



<em>Lenght CD:</em>



<em>Lenght DA:</em>



Therefor the result will be:

Unit rate:
$28 divided by 4kg = $7 per kg
$7 • 14kg = $98
It will cost $98 to buy 14kg of flour.
