Question

A triangle is said to be an equable triangle, if the area of the triangle is equal to the perimeter. Write a program to enter three sides of a triangle. Check and print whether the triangle is equable or not.

Answer 1

Answer:

#include<math.h>

#include <iostream>                        

using namespace std;                      

int main() {

   double s1,s2,s3;

   cout<<"Enter first side ";

   cin>>s1;

   cout<<"Enter second side ";

   cin>>s2;

   cout<<"Enter third side ";

   cin>>s3;

   double s=(s1+s2+s3)/2;

   double ar=s*(s-s1)*(s-s2)*(s-s3);

   double area=pow(ar,0.5);

   double per=s1+s2+s3;

   if(area==per)

   cout<<"It's an equable triangle";

   else

   cout<<"It's not an equable triangle";

   return 0;

}

Explanation:

I have written it in c++

You can implement it any language as you didn't mention the language

find the area and perimeter and equate the values

ex:- sides 6,8,10

It's an equable triangle

Hope it helps :-)
