Question

What is the area of the triangle shown below

Answer 1

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 $\sqrt{18(18-13)(18-13)(18-10)}$

So our final answer is the square root of 3600, which equals 60.
