Program for Area And Perimeter Of Rectangle (original) (raw)

Last Updated : 16 Feb, 2023

A rectangle is a flat figure in a plane. It has four sides and four equal angles of 90 degree each. In rectangle all four sides are not of equal length like square, sides opposite to each other have equal length. Both diagonals of the rectangle have equal length.

Examples:

Input : 4 5 Output : Area = 20 Perimeter = 18

Input : 2 3 Output : Area = 6 Perimeter = 10

Formulae :

Area of rectangle : ab Perimeter of rectangle: 2(a + b)

C++ `

// CPP program to find area // and perimeter of rectangle #include<bits/stdc++.h> using namespace std;

// Utility function int areaRectangle(int a, int b) { int area = a * b; return area; }

int perimeterRectangle(int a, int b) { int perimeter = 2*(a + b); return perimeter; }

// Driver program int main() { int a = 5; int b = 6; cout << "Area = " << areaRectangle(a, b) << endl; cout << "Perimeter = " << perimeterRectangle(a, b); return 0; }

Java

// Java program to find area // and perimeter of rectangle import java.io.*;

class Geometry {

// Utility function
static int areaRectangle(int a, int b)
{
   int area = a * b;
   return area;
}

static int perimeterRectangle(int a, int b)
{
   int perimeter = 2*(a + b);
   return perimeter;
}

// Driver Function
public static void main (String[] args) {

    int a = 5;
    int b = 6;
    System.out.println("Area = "+ areaRectangle(a, b));
    System.out.println("Perimeter = "+ perimeterRectangle(a, b));

}
