Area of the Largest square that can be inscribed in an ellipse in C++

Here we will see the area of largest square that can be inscribed in an ellipse. The square in ellipse will be like below −

The area of ellipse is −

Now, if x and y are same, then

So area is −

Example

#include <iostream> #include <cmath> using namespace std; float area(float a, float b) {    if (a < 0 || b < 0 ) //if values are is negative it is invalid       return -1;    float area = (4*(a*a + b*b)) / (a*a*b*b);    return area; } int main() {    float a = 4, b = 2;    cout << "Area : " << area(a, b); }

Output

Area : 1.25
