Answer :
Heeron's formula states that:-
Semi perimeter (s) = a+b+c/2
Perimeter = [tex] \sqrt (s(s-a) (s-b) (s-c)[/tex]
Semi perimeter (s) = a+b+c/2
Perimeter = [tex] \sqrt (s(s-a) (s-b) (s-c)[/tex]
An important theorem in plane geometry, also known as Hero's formula. Given the lengths of the sides , , and and the SEMIPERIMETER of a triangle ( 1) Heron's formula gives the area of the triangle as ( 2) Heron's formula may be stated beautifully using a caley mengar deteriment as
