Answer 2

#include <stdio.h>

float calarea(float,float);
void calperimeter(float *, float, float);
void display(float, float);
float perimeter1,perimeter2;

int main()
{
float area1,area2;
area1=calarea(2.5,3.5);
area2=calarea(1.5,5.5);
calperimeter(&perimeter1,2.5,3.5);
calperimeter(&perimeter2,1.5,5.5);
display(area1,area2);
return 0;
}
float calarea(float x,float y)
{
float area;
area=x*y;
return area;
}
void calperimeter(float *a,float b,float c)
{
*a=2*(b+c);
return ;
}
void display(float i,float j)
{
printf("\narea = %.2f",i);
printf("\nperimeter = %.2f",perimeter1);
printf("\narea = %.2f",j);
printf("\nperimeter = %.2f",perimeter2);
}

Answer 3
