Question

Abc and def are two simillar triangles such that bc=4cm ef=5cm and area of ∆abc =64 cm then the area of ∆def

Answer 1

if the area is 64cm
∆ABC=64cm
∆DEF=?
BC=4
EF=5
NOW
64×25/16= 100
THE ANSWER

Answer 2

Answer:

Step-by-step explanation:

Then you make an like a+b+c+d+e+f=ab+bc+cd+de+ef+fa then answer is 65cm because 4 is bc of the circle = - so, 64-4 =60 60+5 =65
