Rectangle is 2/5 in. long and 1/3 in. wide.
what is the area of the rectangle
answer in the form of a fraction

 "   in² " . {that is:  " (2/15) in² . "}.

Explanation:
___________________________________________
The formula/equation for the Area of a rectangle:  

A = L * w  ;  

       in which:   L  =  ⅖ in ; 
                       w =  ⅓ in;
___________________________
Find the area;  in a "fraction value" ;
_______________________________
   A = L * w    ;  
 
          →  Substitute the given values for "L" (length) and "w" (width);
       and solve for "A" (area) in the "form of a fraction:
__________________________________________________

A   = (2/15) in  *  (1/3)  in ;
 
→ A    = [(2*1) / (5*3)] *  in * in ; 
______________________________________________________
→    The area is:  "    in² " .
                                          
                                             {that is, "(2/15) in² " .}.
