Question

️ ABC is such that that AB = 3cm , BC = 2cm , CA = 25cm if triangle ️ ABC ️ DEF and EF = 4cm , then perimeter of TRIANGLE ️ DEF is​

Answer 1

Answer:

hope this will help you

Step-by-step explanation:

Given: AB=3cm, BC=2cm and CA=2.5cm and EF=4cm

Also, △ABC∼△DEF

Thus,

DE

AB

=

EF

BC

=

DF

AC

DE

3

=

4

2

=

DF

2.5

Hence, DE=6cm and DF=5cm

Perimeter of Δ DEF = DE+EF+EF

Perimeter of Δ DEF = 4+5+6

Perimeter of Δ DEF = 15 cm
