Final answer:
The length of each cord is 1/10 meter, or 0.1 meter.
Step-by-step explanation:
To find the length of each cord, we divide the total length of the rope by the number of cords. In this case, the length of the rope is 2/5 meters and it is cut into 4 equal cords.
So, the length of each cord is (2/5) / 4 = 1/10 meter, or 0.1 meter.
