WebMay 1, 2024 · Step-by-step explanation: From 3 sides, the area of a triangle is conveniently calculated using Heron's formula: A = √ (s (s -a) (s -b) (s -c)) where s is the semi-perimeter: s = (a+b+c)/2. For the given values of a, b, c, we have ... s = (a+b+c)/2 = (18 +11 +14)/2 = 21.5. A = √ (21.5·3.5·10.5·7.5) = √5925.9375. A ≈ 76.9801 . . . cm^2.
