If Delta ABC is similar to Delta DEF such that BC = 4cm, EF = 5 cm and are a of Delta ABC = 64 cm^(2) find are a of Delta DEF .

If Delta ABC ~ Delta DEF such that area of Delta ABC " is " 9 cm^(2) and the area of Delta DEF " is " 16 cm^(2) and BC=2.1 cm. Find the length of EF.

Let the incircle of a Delta ABC touches sides BC, CA and AB at D,E and F, respectively. Let area of Delta ABC be Delta and thatof DEF be Delta' . If a, b and c are side of Dela ABC , then the value of abc(a+b+c)(Delta')/(Delta^(3)) is

D, E, F are mid points of sides BC, CA, AB of Delta ABC . Find the ratio of areas of Delta DEF and Delta ABC .

Delta ABC is an equilateral triangle. Point P is on base BC such that PC = 1/3BC , if AB = 6 cm, find AP. Delta ABC is an equilateral (ii) AB = 6 cm PC = 1/3 BC

Let the lengths of the altitudes drawn from the vertices of Delta ABC to the opposite sides are 2, 2 and 3. If the area of Delta ABC " is " Delta , then find the area of triangle

In Delta ABC " and " Delta DEF, angle A = angle E and angle B = angle F . Then AB : AC is ……..
