Answer:
profit section and that is answer A
We can always split a regular polygon with
sides into
triangles, whose base is the side of the polygon and whose height is the apothem of the polygon. So, the sum of the areas of all these triangles is

where
is the number of sides,
is the side length, and
is the apothem length.
So, you just need to plug you values in: in your case, you have 
So, the formula becomes

In a simple Cartesian plane, there are two axes, y-axis that is drawn vertically and the x-axis that is drawn horizontally. this problem asks for the an example of horizontal stretch. Thus, the example of horizontal stretch is the stretching of the graph away from the x-axis. Thus, the answer is letter C.
