Question

I need help please and thank you

Answer 1

238

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!

Answer 2

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.
