find the area of a regular polygon in php

To find the area of a regular polygon in PHP, you can use the following function:

main.php
function findAreaOfRegularPolygon($numSides, $sideLength) {
  $apothem = $sideLength / (2 * tan(pi() / $numSides));
  $perimeter = $numSides * $sideLength;
  $area = 0.5 * $apothem * $perimeter;
  return $area;
}

This function takes two parameters:

• $numSides: the number of sides in the regular polygon
• $sideLength: the length of each side of the regular polygon

The function first calculates the apothem of the polygon using the formula apothem = s / (2 * tan(pi / n)), where s is the length of each side, n is the number of sides, and pi is the mathematical constant. It then calculates the perimeter of the polygon using the formula perimeter = n * s. Finally, it calculates the area of the polygon using the formula area = 0.5 * apothem * perimeter and returns it.

You can call this function and pass in the number of sides and the length of each side of the regular polygon to find its area.
