Answer 1

simply use a double or decimal variable and use the √ function and use heron's formulae.. if i give you the codes.. it will be useless.

Answer 2

void main()
{
   int a,b,c,s,ar;
printf("Enter 3 sides");
scanf("%d%d%d",&a,&b,&c);

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

ar=sqrt(s*(s-a)*(s-b)*(s-c));
printf("Area = %d",ar);
