In a C program, translate the following into Chinese: What is the area of ​​the largest triangle that can be embedded within a rectangle?

Suppose a rectangle is given. We know its length L and width B. We have to find the area of ​​the largest triangle that can be inscribed within this rectangle -

The largest triangle is always half the rectangle. So it will be

Example

#include <iostream>
#include <cmath>
using namespace std;
float area(float l, float b) {
   if (l < 0 || b < 0 ) //if the valuse are negative it is invalid
      return -1;
   float area = (l*b)/2;
   return area;
}
int main() {
   float a = 10, b = 8;
   cout << "Area : " << area(a, b);
}

Output

Area : 40
