Answer:
Here S is semi-perimeter of triangle
And a b c are 3 sides
The simple formula for perimeter of triangle is sum of all sides
Hope it help
please mark as brainliest..
Answer:
Area of a Triangle from Sides
You can calculate the area of a triangle if you know the lengths of all three sides, using a formula that has been known for nearly 2000 years.
It is called "Heron's Formula" after Hero of Alexandria (see below)
Just use this two step process:
Step 1: Calculate "s" (half of the triangles perimeter):
s = a+b+c2
Step 2: Then calculate the Area:
herons formula A = sqrt( s(s-a)(s-b)(s-c) )Area of a Triangle from Sides
