C Program for Area And Perimeter Of Rectangle
Given a length and breadth of a rectangle we have to find its area and Perimeter.
Rectangle is 2-D figure containing four sides and four angles of 90 degree each. All the sides of rectangle are not equal only the opposite sides of a rectangle are equal. The diagonals in a rectangle also are of the same length.
Below is a diagrammatic representation of rectangle.
Here A represents the breadth and B represents length of the rectangle.
To find the Area of a rectangle the formula is: Length x Breadth
And Perimeter of a rectangle is − 2 x (Length+Breadth).
Examples
Input: 20 30 Output: area of rectangle is : 600 perimeter of rectangle is : 100
Algorithm
START In Function int area(int a, int b) Step 1 -> Declare an integer ‘area’ and store a * b in it Step 2 -> Return area. In Function int perimeter(int a, int b) Step 1-> Declare an integer ‘perimeter’ and store 2*(a + b) in it Step 2-> Return perimeter In int main() Step 1 -> Declare two integers ‘length’, ‘breadth’ Step 2 -> Print area(length,breadth) Step 3 -> Print perimeter(length, breadth); STOP
Example
#include<stdio.h> //function to calculate area int area(int a, int b) { int area = a * b; return area; } //function to calculate perimeter int perimeter(int a, int b){ int perimeter = 2*(a + b); return perimeter; } int main(){ int length= 20; int breadth = 30; printf("area of rectangle is : %d
",area(length,breadth)); printf("perimeter of rectangle is : %d",perimeter(length, breadth)); return 0; }
Output
area of rectangle is : 600 perimeter of rectangle is : 100
