Question

Is this correct? similar triangles

Answer 1

question attached. my answer:

DEF is 4 times smaller than ABC.

AB and AC = 49

AB is proportional with DE: 49/4 = 12.25

DE and DF = 12.25

ABC is 4 times bigger than DEF.

FE is proportional with CB: 7.5 * 4 = 30

CB = 30

Length of ABC: 49 + 49 + 30 = 128

Length of DEF: 12.25 + 12.25 + 7.5 = 32
