Question

10. If a, b, c are the sides of a triangle and s=semi-perimeter, then area of triangle

​

Answer 1

Answer:

If a b and c are the sides of a triangle,

Then, semi-perimeter= a+b+c/2

using Heron's formula,

Area of the triangle=√s(s-a)(s-b)(s-c).

Hope it will help you.

Answer 2

Answer:

$\sqrt{s(s-a)(s-b)(s-c)}$

Step-by-step explanation:

$s=\frac{a+b+c}{2}$      (semi perimeter of the triangle)
