It means to add
You find the sum of the lengths of each side. 36in 1ft 36in 1ft =
Mean = (sum of the n numbers)/n
Measure each side and add them up to get the sum of the side-lengths = perimeter.

Mean = (sum of the n numbers)/n
You square each number and multiply that by the frequency with which that number appears. You then sum together these results.
Measure each side and add them up to get the sum of the side-lengths = perimeter.
to find the mean of a set of numbers you have to find the total sum of the data divided by the number of addends in the data.
