The lenght and breadth of a rectangle and radius of a circle are input through the keyboard . write a program to calculate the area and perimeter of the rectangle and the area and circumference of the circle.

// program to calculate area of rectangle and circle.

# include<stdio.h>

int main(){

    int l,b,r;

    float rectangle ,circle,area,perimeter,circumference;

    printf("Enter the lenght , breadth:\n ");

    scanf("%d%d",&l,&b);

    rectangle=l*b;

    perimeter=2*(l+b);

    printf("The Area of reactangle is %f and\n

perimeter of rectangle is %f\n",rectangle,perimeter);

    printf("Enter the Radius of the circle:\n");

    scanf("%d",&r);

    circle=3.14*r*r;

    circumference=2*3.14*r;

    printf("The Area of circle is %f

and \nthe circumference of circle is %f",

circle,circumference);

    return 0;

}

/*output*/

Enter the lenght , breadth: 2 3 The Area of reactangle is 6.000000 and perimeter of rectangle is 10.000000 Enter the Radius of the circle: 5 The Area of circle is 78.500000 and the circumference of circle is 31.400000
