If  PQR  is the angle (or an angle),  it can not be  21 cm,  as it is stated in your post.


Make necessary corrections - - - then re-post to the forum.

You mentioned that PQR=21cm, but that doesn't make any sense.

Because three letters are involved, PQR seems to either refer to an angle, or a triangle. Neither of which would make sense to attach "21 cm" to it.

Did you mean to say something like PQ = 21? Or something similar to it?

Please let me know, or revise and make a new post. Thank you.
