Answer:
12 feet.
Explanation:
Ok, so because Myah's chain is 3 times a long, we know Myah's chain is 3 yards.
Now we add Hudson's yard to Myah's 3 yards.
Now we have a total of 4 yards.
However, we need to convert from yards to feet.
There are 3 feet to a yard, so we multiply 4 and 3 to get a total of 12 feet.
