Answer:
the answer is c. 12 inches because first of all you mutliply each option by 4 and then divide by 2 to see if you get 24 and when you do that you get an answer of 12 so 12 is the correct answer and give brainliest to the first people that answer it first than me.
Step-by-step explanation:
6 times 4= 24/2=12
8 times 4= 32/2=16
12 times 4= 48/2=24
20 times 4= 80/2=40
