So we see that the ratio between the two octagons is 7:1, since 28/4=7 so what we do next is multiply the values of the smaller octagon by 7. But that’s the long way. There’s actually a shortcut by multiplying the perimeter of the smaller octagon, 34, by 7. This in turn equals 238.
Answer:
238
Step-by-step explanation:
you have to find the value of each side;
When the question said it is similar,means that either the image is being enlarged or reduced in size
It is given that if the side is 4 in the smaller octagen,the side will be 28 in the larger octagon
Here you can make a ratio and do propotion like what i did.
After finding all value of the sides,add it all up and you can find the perimeter for the larger octagon
Hope this helps!

Jean's car :
(12 1/2) / (5/12) =
(25/2) / (5/12) =
25/2 * 12/5 =
150/5 =
30 miles per gallon
Miranda's car :
(20 5/7) / (5/7) =
(145/7) / (5/7) =
145/7 * 7/5 =
145/5 =
