{ Треугольник задан координатами вершин (x1;y1),(x2;y2),(x3;y3).

Найти площадь треугольника (используя формулу Герона) }

uses crt;

var x1,x2,x3,y1,y2,y3,a,b,c,s,p : real;

begin

clrscr;

write('x1=');readln(x1);

write('y1=');readln(y1);

write('x2=');readln(x2);

write('y2=');readln(y2);

write('x3=');readln(x3);

write('y3=');readln(y3);

a:=sqrt(sqr(x1-x2)+sqr(y1-y2));

b:=sqrt(sqr(x2-x3)+sqr(y2-y3));

c:=sqrt(sqr(x3-x1)+sqr(y1-y3));

p:=(a+b+c)/2;

s:=sqrt(p*(p-a)*(p-b)*(p-c));

write('s=',s);

readln;

end.

формула герона!

А так я думаю эти задачки очень даже не сложные, только формулы надо знать!! !

периметр- это сумма всех сторон

например

begin

writteln( 'введите 3 стороны' ) ;

readln(a,b,c);

writeln(' периметр = ',a+b+c);

readln;

end.

Вот и все!! !

Удачи!
