Age

FrequencyWidth Length of the
rectangle
1 - 25 1 51×1=5
2 - 331 31×1=3
3 - 5 62 62×1=3
5 - 7 12 2 122×1=6
7 - 10 9 3 93×1=3
10 - 15 10 5 105×1=2
15 - 174 2 42×1=2
Width is not constant. So, we have to first calculate the length of rectangle to draw histogram according to the width as shown in the above figure.
