If \(r=\) in radius, \(\triangle=\) Area of \(\triangle A B C, s=\) semi-perimeter then which of the following is true?
- A \(\Delta=r+s\)
- B \(\Delta=\frac{r}{S}\)
- C \(\Delta=(r \mathrm{~s})^2\)
- D \(\Delta=r\) s
Answer & Solution
Correct Answer
(D) \(\Delta=r\) s
Step-by-step Solution
Detailed explanation
Let the length of sides are \(a, b\) and \(c\), so \(s=\frac{a+b+c}{2}\) Now, from the diagram area of triangle \(A B C\) is…
