Apark has a rectangular playground area that has a length of 66 feet and a width of 42 feet . the park department has 75 yards of facing material. is there enough fencing material to enclose the playground area

We first need to know how much fencing would be needed. We can get this from the perimiter of the playground, knowing that it is a rectangle:



then we need to convert to yards to compare to the avialble fencing:



and since 72yd<75yd, yes there is enough fencing.

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
