Will attach a picture of the question cause it has shapes involved

I need help understanding the question, then I think I'll be able to work it out...

I don't understand what trisected means, if the first shape has 3 sides each 9cm long, then the 2nd shape would have 12 sides each ____ long?

trisected means slip into 3 equal parts, similar to the word bisected. therefore each side of the second shape is 3cm. if you think about the transition from the first and second shape, it is equivalent to just adding a whole new side
