Question

If triangle ABC ~triangle DEF, the perimeter of triangle DEF is 20 cm, if one side of triangle ABC is 12cm.
If corresponding side of triangle DEF is 8 cm then perimeter of triangle ABC is​

Answer 1

Answer:

ABC ~ DEF

AB/DE =BC/EF = AC/DF =( AB+BC+CA)/(DE+EF+FD)

AB/DE = perimeter of ABC / perimeter of DEF

12/8= P(ABC)/20

P(ABC)= (12/8)×20

=30
