Per NCERT, what is HERON's FORMULA for the area of a triangle with sides a, b, c and semi-perimeter s?
A(1/2)(a + b + c)
B√[s(s−a)(s−b)(s−c)]
Cs(s−a)(s−b)(s−c)
D√(s² − a² − b² − c²)
Answer & Solution
Correct answer: B. √[s(s−a)(s−b)(s−c)]
Heron's formula: area = √[s(s−a)(s−b)(s−c)]. The other options misstate it.
