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:
129 m/s^2
Step-by-step explanation:
The length of a rectangle is increasing at a rate of 9m/s
dL/dt = 9m/s
The width is increasing at a rate of 7m/s
dw/dt= 7m/s
The formular for solving the area of a rectangle is length × width
Therefore, to calculate how fast the rectangle is increasing we will apply the product rule
dA/dt= L × dw/dt + W × dl/dt
= 12×7 + 5×9
= 84+45
= 129m/s^2
Hence the area of the rectangle is increasing at 129m/s^2
