Answer:
Step-by-step explanation:
By definition:
The pre-meter P of a triangle ABC is equal to the sum of the length of its sides.
We know that:
The perimeter is:
Now we find the length of the sides:
Once the length of the sides is known, we use Heron's formula to calculate the area.
First I find the semiperimeter S.
Then the Area is:
