"WebJan 2, 2024 · The area A of a triangle with sides of length a, b, and c is given by the formula A = √s(s − a)(s − b)(s − c) where s = 1 2(a + b + c). For example, suppose that the lengths of the three sides of a triangle are a = 3ft, b = 5ft, and c = 6ft. Using Heron’s Formula (Equation 3.4.20 ), we get s = 1 2(a + b + c) s = 7 A = √s(s − a)(s − b)(s − c) " - How to solve a triangle in trigonometry
