Answer:

19.5 cm

Explanation:

The median of a data set is the middle number. It can be easily found by crossing out the first value then the ending value, and you keep repeating that pattern. However, in this case, when we cross them out, we're left with the numbers 18 and 21. When we come across a problem like this, we find the mean of 18 and 21 by adding them up and then dividing them by 2. 18 + 21 is 39, and 39/2 is 19.5.

Therefore, the answer is 19.5 cm.

Have a lovely rest of your day/night, and good luck with your assignments! ♡
