The correct answer is: [B]: " 9.6 cm " .
____________________________________________________________

Step-by-step explanation:
____________________________________________________________

Let "FH" = "x" ; for which we wish to solve.

45 cm / 12 cm = 36 cm / "x" (in "cm") ;

To solve for "x" ;

Cross--multiply:

Note: Given:

"
(a)/(b) = (c)/(d)
" ; " ad = bc " ; (b ≠ 0 ; d ≠ 0) ;


So: " 45x = 12 * 36 " ;

→ 45x = 432 ;

Divide each side of the equation by "45" ;
to isolate "x" on one side of the equation; & to solve for "x" ;

→ 45x / 45 = 432 / 45 ;

x = 9.6 cm ;
