Me! the area of the triangle is 48 square centimeters. what is the height of the triangle in centimeters

You have to put 17cm on the other side and then multiply to get the answer

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.

Whose mistake? can you give more details to what the question is asking?
