its the numbers in between... For example: 20<x<=30  class width is 10
                                                          23<x<=29 class width is 6

Length in a histogram is found by this formula:
Frequency density= Frequency/ class width

so

as you will see that 11.5 is found by 115/2 x 5
now do the same process including that >>>> x 5
you will receive the answer ^_^

i got everything exce[t x 5? why x 5?

Ghost Of Highbury:
Again, read the question

"On a histogram, the height of the column for the 20<m<=22 interval is 11.5 cm."

The class is - 20<m<=22

The class width = 2
