Answer:
Check the explanation
Explanation:
#include <bits/stdc++.h>
using namespace std;
class Rectangle{
public:
int length;
int breadth;
Rectangle(int l,int b){
length = l;
breadth = b;
}
int area(){
return length*breadth;
}
int perimeter(){
return 2*(length+breadth);
}
bool equals(Rectangle* r){
// They have the exact same length and width.
if (r->length == length && r->breadth == breadth)
return true;
// They have the same area
if (r->area() == area())
return true;
// They have the same perimeter
if (r->perimeter() == perimeter())
return true;
// They have the same shape-that is, they are similar.
if (r->length/length == r->breadth/breadth)
return true;
return false;
}
};
int main(){
Rectangle *r_1 = new Rectangle(6,3);
Rectangle *r_2 = new Rectangle(3,6);
cout << r_1->equals(r_2) << endl;
return 0;
