给定一个直角三角形,高为l ,底为b和斜边h 。我们需要找到可以放入直角三角形的最大正方形的面积。

例子:

Input: l = 3, b = 4, h = 5
Output: 2.93878
The biggest square that can fit inside 
is of 1.71428 * 1.71428 dimension

Input: l = 5, b = 12, h = 13
Output: 12.4567

以下是所需的实现:

C++
// C++ Program to find the area of the biggest square
// which can fit inside the right angled triangle
#include 
using namespace std;
 
// Function to find the area of the biggest square
float squareArea(float l, float b, float h)
{
 
    // the height or base or hypotenuse
    // cannot be negative
    if (l < 0 || b < 0 || h < 0)
        return -1;
 
    // side of the square
    float a = (l * b) / (l + b);
 
    // squaring to get the area
    return a * a;
}
 
// Driver code
int main()
{
    float l = 5, b = 12, h = 13;
    cout << squareArea(l, b, h) << endl;
 
    return 0;
}


Java
//Java Program to find the area of the biggest square
//which can fit inside the right angled triangle
public class GFG {
 
    //Function to find the area of the biggest square
    static float squareArea(float l, float b, float h)
    {
 
     // the height or base or hypotenuse
     // cannot be negative
     if (l < 0 || b < 0 || h < 0)
         return -1;
 
     // side of the square
     float a = (l * b) / (l + b);
 
     // squaring to get the area
     return a * a;
    }
 
    //Driver code
    public static void main(String[] args) {
         
         float l = 5, b = 12, h = 13;
         System.out.println(squareArea(l, b, h));
    }
}


Python3
# Python 3 Program  to find the
# area of the biggest square
# which can fit inside the right
# angled triangle
 
# Function to find the area of the biggest square
def squareArea(l, b, h) :
 
    # the height or base or hypotenuse
    # cannot be negative
    if l < 0 or b < 0 or h < 0 :
        return -1
 
    # side of the square
    a = (l * b) / (l + b)
 
    # squaring to get the area
    return a * a
 
# Driver Code
if __name__ == "__main__" :
 
    l, b, h = 5, 12, 13
 
    print(round(squareArea(l, b, h),4))
