C++ Program to Find Diagonal of a Rectangle

Given two positive integers i.e, the length and breadth of the rectangle, the task is to find the length of the Diagonal of a Rectangle.

Example:

Input: length=4 breadth=3

output: The Diagonal is 5

The diagonal of a rectangle is sqrt (a*a+ b*b)

C++

// C++ Program to Find Diagonal of a Rectangle
#include <bits/stdc++.h>

using namespace std;

// Function to find the length of the
// diagonal of a rectangle of given sides
double findDiagonal(double a, double b)
{
    return sqrt(a * a + b * b);
}

// Driver Code
int main()
{
    double a = 4, b = 3; // a is the length and b is the
                         // breadth of the rectangle
    cout << "The Diagonal is " << findDiagonal(a, b);

    return 0;
}

Output

The Diagonal is 5

Time Complexity: O(1)

Auxiliary Space: O(1)
