Find the area of a triangle with sides a = 5, b = 8, and c = 11. A. 32.17 B. 12.46 C. 18.33 D. 20.88
The area of a triangle with sides a = 5, b = 8, and c = 11. s = (a + b + c) /2 ; s = (5 + 8 + 11)/2 = 24/2 = 12 ; Area = sqrt ( 12 * (12-5) * (12-8) * (12-11) ) = sqrt ( 12 * 7 * 4 * 1) = sqrt(336) = 18.33
