Find the area of a triangle with sides a = 5, b = 8, and c = 11. A. 12.46 B. 20.88 C. 32.17 D. 18.33

Find the area of a triangle with sides a = 5, b = 8, and c = 11. A. 12.46 B. 20.88 C. 32.17 D. 18.33
A = 5, b = 8, c =11.By Hero's FormulaArea = √(s(s-a)(s-b)(s-c))Where s = (a + b + c) /2s = (5 + 8 + 11)/2 = 24/2 = 12s = 12Area = √(s(s-a)(s-b)(s-c))        =  √(12(12-5)(12-8)(12-11))        =  √(12(7)(4)(1))       = √336           Use your calculator.       ≈ 18.33Option D. ...
