Given one of the Sides S, Diagonal D, or Perimeter P of the square, the task is to find the area of the square with the given value.
Examples:
Input: S = 5
Output: Area of the square using side = 25Input: D = 4
Output: Area of the square using diagonal = 8
Input: P = 32
Output: Area of the square using perimeter = 64
Finding Area of Square using its Side
The area of the square of the side S is given by:
Area = Side * Side
Below is the implementation of the above approach:
C++
// C++ program for the above approach#include <iostream>using namespace std;// Function to find the area of a squareint areaOfSquare(int S){ // Use above formula int area = S * S; return area;}// Driver Codeint main(){ // Given Side of square int S = 5; // Function call cout << areaOfSquare(S); return 0;} |
Java
// Java program for the above approachclass GFG{ // Function to find the area of a squarestatic int areaOfSquare(int S){ // Use above formula int area = S * S; return area;} // Driver Codepublic static void main(String[] args){ // Given Side of square int S = 5; // Function call System.out.println(areaOfSquare(S));}}// This code is contributed by rock_cool |

Finding Area of Square using its Diagonal
- The Area of the square of given side S is given by:
Area = S * S …(1)
- The relation between Side S and Diagonal D is given by:
…(2)
- Substituting the value of S from Equation (2) in Equation (1), we have:
Below is the implementation of the above approach:
C++
// C++ program for the above approach#include <iostream>using namespace std;// Function to find the area of a squareint areaOfSquare(int D){ // Use above formula int area = (D * D) / 2; return area;}// Driver Codeint main(){ // Given diagonal of square int D = 4; // Function call cout << areaOfSquare(D); return 0;} |
