Question

in herons formula √s (s-a) ( s-b) (s-c) where are s,a,b,c and write down the formula of perimeter of triangle​

Answer 1

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 2

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
