The area of a square is simply the square of the side. So, you only need to write a program that receives a number as input, which is the side of the square, and returns that number squared, which will be the area of the square.

scanf("%lf", &side);
} while(side<=0);
area = side * side;
printf("The area is %lf", area);
}
