Question

AABC ~ ADEF. If AB = 12, BC = 10, CA = 8 and EF = 60 then find the
peremeter of the triangle ADEF.​

Answer 1

Answer:

In the given figure, let CE=CF=x

It is also given that AB=12 cm, BC=8 cm and AC=10 cm, therefore,

AF=AD=10−x

BE=BD=8−x

Now consider,

AB=AD+BD

⇒12=10−x+8−x

⇒12=18−2x

⇒2x=18−12

⇒2x=6

⇒x=
