Questions:
Which of the four different Before conditions would you actually have? It makes a big difference to the approach, whether an "entry" consists of one Text object or two, and/or whether parentheses are involved.
Does the After really make no reference to the SZxx name in each case? In the case of the SZxx being a separate Text object from the YY/ZZ [or (YY/ZZ)] part, does the SZxx part have any relevance at all?
What would be the User procedure? Call a defined-command name, and then ... ?
Assuming the two numbers such as 30 and 60 are extracted from a Text string and put into variables called n1 and n2, in AutoLisp terms and reduced down to what it really amounts to, L would be (* (+ n1 n2 1) 2).

Sxx does not have a name like YY or ZZ.

[I'm not sure what you mean by that part. My YY/ZZ was a stand-in for 30/60, 60/30, 40/40, 30/95, whatever.]
One question is still unanswered, and I have another: Would the numbers always be 2 digits?
Still no answer on the User procedure, and related issues. The User selects a Text object? Or a bunch of them at once? Or the routine finds them all, based on some criterion [that they contain a YY/ZZ part, and/or by their Layer or Style, or...]? Will they always be in vertical columns or at least always with space to their right so the added Text won't overlap something? Would the Layer for the new Text be built into the code, or would the User be asked to specify it, or would it be the same as the selected Text? LIkewise for the Style and height. Would the added Text be in a different color, as in your sample drawing, or was that just to visually differentiate before from after? Etc., etc.

That's a lot easier than having to figure out somehow whether to put results beside or below [what if some would need to be in one direction and some in the other?]. Try this [minimally tested], which asks you to position the first 5ø8 Text for the top of the column of results:
(defun C:STIRLEN (/ ss txt ht hor ver n ref str n1 n2); = STIRrup LENgths
(if
(setq ss (ssget '((1 . "*##/##*"))))
(progn ; then
(command "_.copy" (ssname ss 0) "" '(0 0 0) ""); in place
(setpropertyvalue (setq txt (entlast)) "TextString" "5ø8")
(setpropertyvalue txt "Color" 3)
(alert "Position Text for top of vertical column of values.")
(command-s "_.move" txt "" "_non" (getpropertyvalue txt "Position"))
(setq
ht (getpropertyvalue txt "Height")
hor (* ht 3)
ver (* ht 1.5)
); setq
(repeat (setq n (sslength ss))
(setq
ref (ssname ss (setq n (1- n)))
str (getpropertyvalue ref "TextString")
str (substr str (1- (vl-string-search "/" str)) 5); ##/## part only
n1 (atoi (substr str 1 2))
n2 (atoi (substr str 4))
); setq
(command "_.copy" txt "" "_non" (polar '(0 0) 0 hor) "")
(setpropertyvalue (entlast) "TextString" (strcat "L=" (itoa (* (+ n1 n2 1) 2))))
(if (> n 0)
(progn ; then
(command "_.copy" txt "" "_non" (polar '(0 0) (* pi 1.5) ver) "")
(setq txt (entlast))
); progn
); if
); repeat
); progn
); if
(prin1)
); defun
The second setting of the 'str' variable [done in a way that doesn't care whether there are parentheses and/or a SZ## prefix], and the setting of 'n1' and 'n2', are why it matters that the numbers are always and only 2 digits each.

Try this code. Select texts with a format similar to the second attached file
(defun c:l_s (/ s lst i sn tx pr cx a b l rs pins)
(princ "Select texts with <SZxy (ij/kl)> format: ")
(setq s (ssget '((0 . "text")))
lst ()
)
(repeat (setq i (sslength s))
(setq sn (entget (ssname s (setq i (1- i))))
tx (cdr (assoc 1 sn))
pr (substr tx 1 4)
cx (substr tx 7 5)
a (atof (substr cx 1 2))
b (atof (substr cx 4 2))
l (rtos (+ (* 2 (- a 6)) (* 2 (- b 6)) (* 2 13)) 2 2)
rs (strcat pr " L= " l "\\P")
lst (cons rs lst)
)
)
(setq ltx (apply 'strcat (vl-sort lst '<))
pins (getpoint "\nPickpoint: ")
)
(entmakex (list '(0 . "MTEXT")
(cons 100 "AcDbEntity")
(cons 100 "AcDbMText")
(cons 10 pins)
(cons 40 20)
(cons 1 ltx)
(cons 11 '(1. 0. 0.))
)
)
)
