Question

Write a java program to print the area and perimeter of a triangle along with appropriate messages. Make use of proper variables.
Hint: Area of triangle = ½ * base * height; Perimeter of triangle = side1 + side2 + side3​

Answer 1

Explanation:

class triangle{

public:

void print_perimeter(int s1,int s2,int s3){

int s;

s= s1+s2+s3;

cout<<"perimeter is "<<s<<endl;

}

void print_area(int s1,int s2,int s3){

int s= (s1+s2+s3)/2;

double area;

area= sqrt( s*(s-s1)*(s-s2)*(s-s3) );

if ((s1+s2)<s3 || (s1+s3)<s2||(s2+s3)<s1 )

{cout<<"invalid triangle";

}

else

{

cout<<"area is: "<<area<<endl;

}

}

};

int main(){

triangle t1;

t1.print_perimeter(3,4,5);

t1.print_area(1,10,12);

return 0;

}
