Answer:
B is the correct answer
Step-by-step explanation:
Answer: 60
Step-by-step explanation:
Using Heron's formula, we know that
Step 1: Calculate "s" (half of the triangles perimeter):
s = (a+b+c)/2
Step 2: Then calculate the Area:
Herons formula A = sqrt( s(s-a)(s-b)(s-c) )
So S = 36/2 = 18
so ![\sqrt{18(18-13)(18-13)(18-10)}](https://tex.z-dn.net/?f=%5Csqrt%7B18%2818-13%29%2818-13%29%2818-10%29%7D)
So our final answer is the square root of 3600, which equals 60.
