The formula of area of a triangle is defined by heron and it is also known as Heron's formula.
Area of Triangle = √s(s-a)(s-b)(s-c
s = Perimeter of triangle/2
s = (a+b+c)/2
where a, b and c are the sides of the triangle and ‘s’ is the semiperimeter.
Perimeter = The perimeter of a rectangle is the sum of its all sides.
