```							dear aditi, aruns answer is totally crap and you shall get zero marks for such a solution. he has simply taken a special case of equilateral triangle. but we need to prove for general triangle.we know the standard formulas:r1= A/(s – a), r2= A/(s – b), r3= A/(s – c) where A is area of triangle and s is semiperimeter, 2s= a+b+cR= abc/4Aalso, by heron formulaA^2= s(s – a)(s – b)(s – c)substitute these values and simplify, we getA^3*abc/R(s(s – a)(s – b)(s – c))^2= 4A^4/(A^2)^2= 4A^4/A^4= 4kindly approve :))
