Question

write heron's formula to find area triangle and explain what s denotes​

Answer 1

Step-by-step explanation:

s =(a+b+c)/2

area of ∆=√{s(s-a)(s-b)(s-c)}

Answer 2

$\sf\underline{Heron's~formula:}$

Formula for finding the area of a triangle when height isn't known was given by Heron with help of lengths of sides a, b and c

$A = \sqrt{S(S - a)(S - b)(S - c)}$

Where, S is the perimeter of triangle divided by 2

[sum of sides of triangle divided by 2]

$S = \frac{a + b + c}{2}$

Have a nice evening!
