Three sides of one and three sides of another triangle are given. Determine whether these triangles

Three sides of one and three sides of another triangle are given. Determine whether these triangles will be of equal size, i.e. whether they have equal areas. in the pascal system

Areas in the program are calculated according to Heron’s formula.

program area1;
var a, b, c, p, s1, s2: real // a, b, c – sides of a triangle, p – semiperimeter,
// s1, s2 – areas of triangles;
begin

for i: integer: = 1 to 2 do

begin

writeln (‘Enter the lengths of the three sides of the first triangle’);
read (a, b, c);
p: = (a + b + c) / 2;
s1: = sqrt (p * (p – a) * (p – b) * (p – c));

end

writeln (‘Enter the lengths of the three sides of the second triangle’);
read (a, b, c);
p: = (a + b + c) / 2;
s2: = sqrt (p * (p – a) * (p – b) * (p – c));

if s1 = s2 then writeln (‘The areas of the triangles are equal’) else
writeln (‘The areas of the triangles are different’)

end.
