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

If area of ' formed by joining mid-points of the sides of Delta ABC is 2sq. Units. Then are of Delta ABC = (a)8 (b)4 (c)2 (d)1

Points E and F lie respectively on side AC and AB of a triangle ABC such that EF||BC and 2EF=BC . If G be the centroid of DeltaABC then find the area of triangle formed by joining mid points of sides of triangle EFG with respect to area of DeltaABC .

If G is the centroid of DeltaABC and if area of DeltaAGB 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
