Hello there!
A vegetable garden is 12 meters long by 7 meters wide. It is home 168 mice. What is the population of the mice.
The size of the vegetable garden is just extra information.
The only information we need is: "It is home 168 mice"
This means the population of mice is 168. Meaning, there are 168 mice living there.
I hope I helped!
Let me know if you need anything else!
