The length of one shoelace is 20cm and half a shoelace.
What is the length of 2 such shoelaces?
Answer
The length of 2 such shoelaces is 80cm.
If the length of one shoelace is 20cm and half a shoelace, the other half is 20cm in length. So, one shoelace is 40cm long and therefore, 2 such shoelaces will be 80cm long.
