Heron's Formula
Given: three sides
A= sqrt(s(s-a)(s-b)(s-c)
where s= (a+b+c)/2
find the semi perimeter
s= (94 + 102 + 150)/2
s= 173
Substitute the value of s to Heron's formula
{A= sqrt(173(173-94)(173-102)(173-150)}
A = 4724.215 sq. units

-------------
Use the Cosine Law to find the angles.
c%5E2+=+a%5E2+%2B+b%5E2+-+2ab%2Acos%28C%29
Find 2 angles, then the 3rd is 180 - (other 2)
