Area

Adapted by Neilor Tonin, URI  Brazil | Timelimit: 1

Make a program that reads three floating point values: A, B and C. Then, calculate and show:
a) the area of the rectangled triangle that has base A and height C.
b) the area of the radius’s circle C. (pi = 3.14159)
c) the area of the trapezium which has A and B by base, and C by height.
d) the area of ​​the square that has side B.
e) the area of the rectangle that has sides A and B.

Input

The input file contains three double values with one digit after the decimal point.

Output

The output file must contain 5 lines of data. Each line corresponds to one of the areas described above, always with a corresponding message (in Portuguese) and one space between the two points and the value. The value calculated must be presented with 3 digits after the decimal point.

Solution

#include <stdio.h>
#define pi 3.14159

int main()
{


    double A,B,C,m,n,o,p,q;


    scanf("%lf%lf%lf",&A,&B,&C);

    m = 0.5*A*C;
    n= pi*C*C;

    o=(A+B)/2*C;
    p=B*B;
    q=A*B;

    printf("TRIANGULO: %.3lf\n",m);
    printf("CIRCULO: %.3lf\n",n);
    printf("TRAPEZIO: %.3lf\n",o);
    printf("QUADRADO: %.3lf\n",p);
    printf("RETANGULO: %.3lf\n",q);

    return 0;
