Before starting any code, you should learn to use google first. Good luck :)

Area of a square and rectangle don't have different formula. That's what my teacher taught me at 5th standard. Why you want it separate

have tries google
then also seen below

Program to calculate area of geometric figures.

do you have a C?

**Dalek Dave** · Answer 3 · 2011-03-10T14:24:00

Solution 3

Square = l^2
Rectangle = l*w
Circle = πr^2

What more do you need?

Just define the variables and apply the formulae.

Simples.

can you check if i have a mistake here. the answers are all zero

#include<stdio.h>

int l,wd,r,s;
double pi=3.14;

double Rectangle()
{
double rec;
rec=l*wd;
return(rec);
}

double Square()
{
double squ;
squ=s*s;
return(squ);
}

double Circle()
{
double cir;
cir=pi*(r*r);
return(cir);
}

void entry()
{
printf("Enter length\t: ");
scanf("%d",&l);
printf("Enter width\t: ");
scanf("%d",&wd);
printf("Enter radius\t: ");
scanf("%d",&r);
printf("Enter side\t: ");
scanf("%d",&s);
}

main()
{
double area;
clrscr();
entry();
printf("\n");
area=Rectangle();
printf("The area of Rectangle is : %g\n",area);
area=Square();
printf("The area of Square is\t : %g\n",area);
area=Circle();
printf("The area of Circle is\t : %g\n",area);
getch();
}
