Calculate the area of ​​leaves within a square in C program

To find the area of ​​a leaf within a square, we need to divide it into several parts and find the area of ​​each part, and then add these areas to get the area of ​​the leaf.

To calculate the area, we need to divide the leaf into two parts.

To find the area of ​​the first part AECA, we will find the area of ​​the quadrilateral AECDA and subtract the area of ​​the triangle ACDA from it.

Quadrant area = 1⁄4 *(π*r²) where

π = 22/7 or 3.141.

Area of ​​a right triangle = 1⁄2*B*H = ½ a²

Example

#include
#define PI 3.14159265
int main() {
   float a = 12.3;
   float area= a * a * (PI / 2 - 1);
   printf("area = %f", area);
   return 0;}

Output

area = 86.355782
