In ` Delta ABC`, D, E, F are the mid points of `AB, BC, CA` respectively. If `AB=6cm BC=7.2cm, CA=7.8 cm` find perimeter of ABC

In a triangle ABC,D and E are the mid- points of BC,CA respectively.If AD=5,BC=BE=4, then CA=

In Delta ABC, D, E, F are mid-points of AB, BC, CA respectively and angle B = 90^@ , AB = 6 cm, BC = 8 cm. Then area of Delta DEF (in sq.cm) is

In a Delta ABC, D, E and F are the mid-point of sides BC, CA and AB respectively. If area of Delta ABC = 16 cm^(2) , find the area of trapezium FBCE

In a DeltaABC , D, E and F are the midpoints of BC, CA and AB respectively. If the lengths of side AB, BC and CA are 7 cm, 8 cm and 9 cm respectively, the perimeter of DeltaDEF is a cm. The value of a/2 is

A circle touches the side BC of Delta ABC at F and touches AB and AC at D and E, respectively. If AD = 8 cm, then find the perimeter of Delta ABC .
