Similarity 80742

Calculate the perimeter of triangle ABC if you know that it is similar to triangle EFG in which e=144 mm, f=164 mm, g=92 mm, and the similarity ratio is 4. Express the result in cm.

Correct answer:

o1 =  160 cm

Step-by-step explanation:

e=144 mm cm=144:10  cm=14.4 cm f=164 mm cm=164:10  cm=16.4 cm g=92 mm cm=92:10  cm=9.2 cm  o2=e+f+g=14.4+16.4+9.2=40 cm r=4  r = o1:o2  o1=r o2=4 40=160 cm
