If the area of the triangle formed by joining the midpoints of the sides of DeltaABC is 5 sq.unit, then the area of DeltaABC is

Assertion (A) : The radius of the circle inscribed in the triangle obtained by joining the middle points of the sides of DeltaABC is equal to half the radius of incircle of DeltaABC Reasons (R): In DeltaABC D, E, F be midpoints of the sides of DeltaABC, Delta 2s s denote area and perimeter of DeltaDEF then Delta=Delta//4= and s=s//2

Assertion (A) : The radius of the circle inscribed in the triangle obtained by joining the middle points of the sides of Delta ABC is equal to half the radius of incircle of Delta ABC Reason (R ) : In Delta ABC, D,E,F be midpoints of the sides of Delta ABC , Delta ' , 2s' denotes area and perimeter of Delta DEF " then " Delta ' = Delta//4 and s' =s//2
