In Heron's formula what is the semiperimeter s of a triangle equal to?

हीरोन सूत्र में त्रिभुज का अर्धपरिमाप s किसके बराबर होता है?

A. a + b + c / a + b + c B. (a + b + c)/2 / (a + b + c)/2 C. ab + bc + ca / ab + bc + ca D. abc / abc
Show answer and explanation
Correct Answer

B. (a + b + c)/2 / (a + b + c)/2

Explanation

The semiperimeter is half of the perimeter so s = (a + b + c)/2.

अर्धपरिमाप परिमाप का आधा होता है इसलिए s = (a + b + c)/2।
