Step-by-step explanation:
The area of the triangle ABC is 81. 33 square units.
We have to determine
What is the area of triangle ABC?
<h3>
What is the formula for the area of a triangle?</h3>
The area of the triangle is determined by;
![\rm Area \ of \ triangle = s\sqrt{s(s-a)(s-b)(s-c)}](https://tex.z-dn.net/?f=%5Crm%20Area%20%5C%20of%20%5C%20triangle%20%3D%20s%5Csqrt%7Bs%28s-a%29%28s-b%29%28s-c%29%7D)
Where the value of s is = a + b + c= 12 + 14 + 16 = 42
Substitute all the values in the formula;
![\rm Area \ of \ triangle = \sqrt{s(s-a)(s-b)(s-c)}\\\\\rm Area \ of \ triangle = \sqrt{21(21-12)(21-14)(21-16)}\\\\\rm Area \ of \ triangle = \sqrt{(21 \times 9 \times 7 \times 5)}\\\\Area \ of \ triangle =\sqrt{6,615}\\\\Area \ of \ triangle = 81.33](https://tex.z-dn.net/?f=%5Crm%20Area%20%5C%20of%20%5C%20triangle%20%3D%20%5Csqrt%7Bs%28s-a%29%28s-b%29%28s-c%29%7D%5C%5C%5C%5C%5Crm%20Area%20%5C%20of%20%5C%20triangle%20%3D%20%5Csqrt%7B21%2821-12%29%2821-14%29%2821-16%29%7D%5C%5C%5C%5C%5Crm%20Area%20%5C%20of%20%5C%20triangle%20%3D%20%5Csqrt%7B%2821%20%5Ctimes%209%20%5Ctimes%207%20%5Ctimes%205%29%7D%5C%5C%5C%5CArea%20%5C%20of%20%5C%20triangle%20%3D%5Csqrt%7B6%2C615%7D%5C%5C%5C%5CArea%20%5C%20of%20%5C%20triangle%20%3D%2081.33)
Hence, the area of the triangle ABC is 81. 33 square units.
