Kvadratning tomoni a berilgan. Uning perimetri aniqlansin

Begin 1. Kvadratning tomoni a berilgan.Uning perimetri aniqlansin.	#include using namespace std; int main() { int a,p; cout<<"kvadratning tomonini kiriting "< cout<<"a=";cin>>a; p=4*a; cout << "kvadratning perimetri= "<< p << endl; return 0; }
Begin 2. Kvadratning tomoni a berilgan.Uning yuzasi aniqlansin.	#include using namespace std; int main() { int a,s; cout<<"kvadratning tomonini kiriting "< cout<<"a=";cin>>a; s=a*a; cout << "kvadratning yuzasi= "<< s << endl; return 0; }
Begin 3.To’g’ri to’rtburchakning tomonlari a va b berilgan.Uning yuzasi va perimetri aniqlansin.	#include using namespace std; int main() { int a,b,s,p; cout<<"a=";cin>>a; cout<<"b=";cin>>b; s=a*b; p=2*(a+b); cout << "kvadratning yuzasi= " << s << endl; cout << "kvadratning perimetri= "<< p << endl; return 0; }
Begin4. Aylananing diametri berilgan. Uning uzunligi ni topish dasturi tuzilsin. Bu yerda .	#include using namespace std; int main() { float d,l; float const pi=3.14; cout<<"aylaning diametrini kiriting=";cin>>d; l=pi*d; cout << "aylaning diametri= " << l<< endl; return 0; }
