Question

what is formula of area of triangle

Answer 1

the formula of area of triangle is base x height /2
                                            or
altitude x base /2

Answer 2

Area of triangle = 1/2*base*height .

Area of triangle = $\sqrt s(s-a)(s-b) (s-c)$

a, b , c are the lengths of sides of the triangle .

Area of triangle = √3/4 a² [ for equilateral triangle of side 'a']

Area of triangle = 1/2a² [ for isosceles triangle with base and height are " a " ]
