2. (B) Write a program to find the area of rectangle, square and circle.

2. (B) Write a program to find the area of rectangle, square and circle.

Area of Circle:

	#include<stdio.h> int main() {
	float radius, area;
	printf("\nEnter the radius of Circle : ");
	scanf("%d", &radius);
	area = 3.14 * radius * radius;
	printf("\nArea of Circle : %f", area);
	return (0);
	}

Area of Square:

#include<stdio.h>

	int main() {
	int side, area;
	printf("\nEnter the Length of Side : ");
	scanf("%d", &side);
	area = side * side;
	printf("\nArea of Square : %d", area);
	return (0);
	}

Area of Rectangle:

#include<stdio.h>
	#include<conio.h>
	int main() {
	int length, breadth, area;
	printf("\nEnter the Length of Rectangle : ");
	scanf("%d", &length);
	printf("\nEnter the Breadth of Rectangle : ");
	scanf("%d", &breadth);
	area = length * breadth;
	printf("\nArea of Rectangle : %d", area);
	return (0);
	}
