Answer:
The length in meters would be 1/20 meters, which is 50 centimeters.
Explanation:
In order to find this, multiply the perimeter by 1/4, since each side will be 1/4 of the overall side.
1/5 * 1/4 = 1/20
Now that we have this, we can multiply by 1000 to get the number of centimeters.
1/20 * 1000 = 50 centimeters
