The altitudes from `A` `B` ,`C` to opposite sides of `triangle ABC` are `24,18,(72)/(5)` respectively. If `delta` is area of `/_\ ABC` . Then `root(3)(delta)=`

The length of the altitudes from the vertices A,B,C of a triangle ABC to opposite sides are 24,18,(72)/(5) respectively. If Delta is the area of the triangle ABC then root(3)(Delta) is equal to

The mid points of sides of a triangle ABC are (2,1),(3,-1) and (0,0) .The area of triangle ABC is

If the mid-points P,Q and R of the sides of the Delta ABC are (3,3),(3,4) and (2,4) respectively,then Delta ABC is

If a,b,c are sides of Delta ABC are in A.P.then

The altitudes from the vertices A,B,C of an acute angled triangle ABC to the opposite sides meet the circumcircle at D,E,F respectively . Then (EF)/(BC) =

The vertices of ABC are (-2,1),(5,4) and (2,-3) respectively.Find the area of the triangle and the length of the altitude through A.

In a scalene triangle ABC , AD and CF are the altitudes drawn from A and C on the sides BC and AB repectively.If the area of the triangle ABC and BDF are 18sq.units and 2 sq. units respectively and DF = 2sqrt2 , then R =
