The answer is:  "25 feet" 
____________________________________________
Explanation:
___________________________________________

Perimeter  = 2*(length) + 2*(width); 

or;  "P = 2L + 2w " ;.
____________________________________________
In this case:  

"P = (2L + 2w) − 2 ⅚ " ; solve for "P" ; all units are in "feet (ft)" ;
____________________________________________________
From the diagram; we are given:
____________________________________________________
  L = 12 ¼ ;
 
  w = 10 ; 
____________________________________________________

        →   " P = { [2* (12 ¼) ] + [2* 10] }  − 2 ⅚  " ;  Solve for "P" ;
__________________________________________________________
Note:  Rewrite "12 ¼" ;  AND:  "2 ⅚" as "improper fractions" :
_________________________________________________________
→ " 12 ¼ = [ (4*12) + 1 ] / 4 =  =  "  ;

→ " 2 ⅚  = [ (6*2) + 5 ] / 6 =  =  "   ;
_________________________________________________________ 
Rewrite our equation: 

→   " P = { [2* (12 ¼) ] + [2* 10] }  − 2 ⅚  " ;;

substituting the "mixed numbers" with "improper fractions" ;
→   " P = { [2* () + [2* 10] }  −  " ;
________________________________________________________
→ Note: " 2* ;

                   =  * " ;

The "2" in the "    " 
      cancels to "1" ; and the "4" in the " " 
     cancels to "2" ;  {Since:  "(4÷2=2)" ; and since:  "(2÷2=1)" ;

    →  and we have:   " 2* = "    " .
___________________________________________________
Note:  {2*10] = 20 .
___________________________________________________
So; we can rewrite our equation as follows:
___________________________________________________
→ " P =    +  20 −  " ;  
___________________________________________________
Now, multiply the entire equation (both sides) by "6" ;
                                        to get rid of the fractions;
____________________________________________________
→ 6*{P =    +  20 − } ;
____________________________________________________
to get:
____________________________________________________
  → 6P = ( *49)  +  20  −  (6*) ;

  → 6P = (3 * 49) + 20  −  ( * 17) ;

             →  6P = ( 3 * 49) + 20  −  (1 * 17)  ;

             →  6P = ( 3 * 49) + 20  −  (1 * 17)  ;

             →  6P =  (147) + 20 − 17 ;

             →  6P = 147 + 20 − 17 ;

             →  6P  = (147 + 20) − 17 ;
 
             →  6P = 167 − 17 ;

             →  6P = 150 ;
__________________________
Now, divide EACH SIDE of the equation by "6" ; to isolate "P" on one side of the equation; and to solve for "P" (which is our answer, in units of "feet" (ft). ;
__________________________
             → 6P / 6  =  150 / 6 ;

to get:  →   P = 25 .
_____________________________________________
The answer is:  "25 feet" .
