Answer:
12
Step-by-step explanation:
The multiplier to get from 6 * ... to 15 is 15/6.
If 6 * 15/6 = 15, then 20 * 15/6 = 50, answer B.
Two meters is greater because there are about 79 inches in two meters and when you do 6 x 12 you get 72 inches, so six feet are less than two meters. Vice versa if you wanted the smaller length.
