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!

slava [35]
There are 6 children total, 4 of which are girls. The ratio is 2:1 girls:boys, so there will need to be twice as many pinks as there are blues. If we get 12 pinks, then there will be 6 blues. That's the biggest since that's all the pinks the florist has.
