It should be noted that a polygon is a flat two dimensional closed shape that has straight sides.
<h3>What is a polygon?</h3>
Your information is incomplete. Therefore, an overview of a polygon will be given.
A polygon simply means a plane figure which is described by a finite number of straight line segments that are connected in order to form a closed polygonal chain.
In this case, the length of a line segment can be measured by simply measuring the distance between the two endpoints.
It's simply the path between two points that has a definite length that can be measured.
Examples of polygon include triangles, quadrilateral, pentagon, etc.

Answer:
13a
Step-by-step explanation:
9a + 3a + a = 13a
The length of BC = 72
Solution:
Given ΔABC and ΔDEF are similar triangles.
ΔABC ΔDEF
AB = 54, BC = n, EF = 12, DE = 9
Similar triangle theorem:
If two triangles are similar then the corresponding sides are proportional to each other.
Substitute the given values, we get
Do cross multiplication.
Divide both sides of the equation by 9.
⇒ BC = 72
Option B is the correct answer.
The length of BC = 72.
