 If lengths of three sides of a triangle are input through the keyboard write a program to find the area of triangle.

//Find the area of triangle  ,given the sides.

#include <stdio.h>

#include<math.h>                //for sqrt()

int main() 

{

float a,b,c,sp, area;

printf("\nEnter sides of a triangle:");

scanf("%f%f%f",&a,&b,&c);

sp =(a+b+c)/2;

area=sqrt(sp*(sp-a)*(sp-b)*(sp-c));

printf("Area of triangle=%f\n",area);

return 0;

}

output--- Enter sides of tringle: 4   5   6

                Area of triangle= 9.921567

 





paper of size A0 has dimensions 1189 mmx 841 mm .Each subsequent size A(n) is defined as A(n-1) cut in half parallel to its shorter sides .Thus paper of size A1 would have dimensions 841 mm X 594 mm .Write a program to calculate the print paper sizes A0,A1,A2,.........A8.
