Question

Area of triangle-/s(s+ a)(s + b)(s + c), where S is semi-perimeter.









what is answer ​

Answer 1

Answer:

this is an herons formula for finding the area of triangle

Answer 2

Answer:

The area of a triangle is defined as the total region that is enclosed by the three sides of any particular triangle. Basically, it is equal to half of the base times height, i.e. A = 1/2 × b × h. Hence, to find the area of a tri-sided polygon, we have to know the base (b) and height (h) of it.

A formula does exist that can calculate the area of a triangle when all three sides are known. This formula is attributed to Heron of Alexandria but can be traced back to Archimedes. Area=SQRT(s(s-a)(s-b)(s-c)), where s=(a+b+c)/2 or perimeter/2.
