Bo’lgan to‘g‘ri to‘rtburchak berilgan, uning yuzasi

3. Tomonlari a va b bo’lgan to‘g‘ri to‘rtburchak berilgan, uning yuzasi s va perimetri p
hisoblansin

Dastur kodi:

#include

#include
using namespace std;
int main(){
int s, p, b, a;
cout<<"a= ";
cin>>a;
cout<<"b= ";
cin>>b;
p=2*(a+b);
s=a*4;
cout<<"p="<

cout<<" s = "< return 0;
}

Natija

13. Radiuslari r1 va r2 bo‘lgan (r1>r2) hamda markazlari umumiy 2 ta doira berilgan.
Birinchi doiraning yuzi s1, ikkinchi doiraning yuzi s2 hamda tashqi doiraning ichida va
ichki doiraning tashqarisida joylashgan yuza s3 (s3=s1-s2)
hisoblansin.

#include

#include
using namespace std;
int main(){
int s1, s2, s3, r1, r2;
cout<<"r1= ";
cin>>r1;
cout<<"r2= ";

s1=3.14*r2*r2;
s2=3.14*r1*r1;

19. To‘g‘ri burchakli to‘rtburchakning qarama-qarshi uchlarining koordinatalari (x1,y1) va
(x2,y2) lar berilgan. To‘g‘ri to‘rtburchakning tomonlarini koordinata o‘qlariga parallel deb
hisoblanib, uning perimetri va yuzasi hisoblansin.
