Where do you need help? Where did you get lost?
Multiply (13.2 cm) by (1 inch/2.54 cm). That gives you the whole length in inches. If it's more than 12, then take as many 12s away from it as you can, and call each of those '1 foot'. When you can't take 12 away any more, then what you have left is the inches.
24-4m=42m-24+2
24+24-2=42m+4m
46=46m
m=1
