4
9
15
16

Answer 1

The number of trees which are less than 20 meters are:

9

Explanation:

Based on the histogram we are asked to find the number of trees which are less than 20 meters in height.

Class interval Frequency

4-8 1

8-12 2

12-16 2

16-20 4

20-24 6

24-28 4

28-32 2

i.e. we are asked to find the total number of tress that lie in the class interval 4-20.

i.e. we add the frequencies that lie in the interval 4-20

i.e. Number of trees= 1+2+2+4=9 trees.
