Peters String

Hi!

Yesterday, for math, we did work on a slide about Peters string.

All we had to do was answer the questions, show our working out then show the answer.

I didn't find it that hard but it was a bit confusing since 

I did it at home because I wasn't at school that day.

Because of that I don't know if I did it right or wrong.

Here is my work.

Then if we finished we had to do the extension.

Here is the rest of my work.

That was my work.

I hope I did it right.

Feel free to comment if you think I answered it 

right or wrong with your working out.

I think I answered them right but it hasn't been marked yet so I don't know.

Bye!
