In a `DeltaDEF`, A, B and C are mid points of EF,FD and DE respectively. IF the area of `DeltaDEF` is 14.4 `cm^2` then find the area of `DeltaABC`.

In DeltaABC , D, E and F are the mid points of the sides, then DeltaDEF =

DeltaABC~DeltaDEF ,BC=3cm, EF=4cm and area of DeltaABC = 54 cm^2 . Determine the area of DeltaABC .

DeltaPQR is an equilateral triangle.X,Y,Z are the mid points of the sides and A,B,C are mid-points of sides of DeltaXYZ . If the perimeter of DeltaPQR is 8.4cm., then the perimeter of DeltaABC =

In the rectangle ABCD, X, Y are the mid points of barCD , barAD respectively. Area of rectangleABCD is 64 cm^2 . If AB=16 cm,then the distance be tween bar(AB) , bar (CD) is

In /_\ABC , P, Q, R are the mid points of bar(AB), bar(BC), bar(CA) respectively. If area of /_\POR=3 sq. units. Find the area of the /_\ABC .

Internal bisectors of DeltaABC meet the circumcircle at points D, E and F then area of DeltaDEF is

In the given DeltaABC , points D and E are mid points of AB and AC and also BC=6 cm then find DE.
