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 
So our final answer is the square root of 3600, which equals 60.
That is an arithmetic sequence of the form:
a(n)=2n-1
Now the sum of an arithmetic sequence is just the average of the first and last terms times the number of terms...
We know the first term is 1, let's find the last term...
a(1000)=2(1000)-1=1999
So the sum of that sequence is:
1000(1999+1)/2
1,000,000
