Lateral surface area of the regular pyramid through the height

A pyramid is considered correct if its base is a regular polygon at, it follows that all its edges are equal to each other, if the height of the pyramid is known, then in order to find the area you first need to calculate the apothem, this is possible by Pythagorean theorem, since by connecting the height and the apothem we get a right triangle. Substituting, we obtain the formula of the area of the lateral surface of the pyramid through the height.
