Which year group or maths challenge would these questions be targeted at?

Anyone experienced out there, please suggest what level UKMT this might be pitched at I'd be so grateful. many thanks.

A right-angled triangle starts out in position (1). It is rotated about point 𝐴 into
position (2). It is then rotated about point 𝐵 into position (3). Finally, it is rotated
about point 𝐶 into position (4). Given that 𝐴𝑃 = 𝐵𝑃 = 𝐶𝑃 = 10 cm, find the total
length of the path traced out by point 𝑃. Take 𝜋 = 3.14. (Pic attached)

What a crock of old shit. 😬. Total waste of time

DD does a lot these challenges and I would say that that looks like hard-end of the intermediate maths challenge, or medium end of senior maths challenge.

Thanks @Retrecir. That's very helpful.
