To find the total width of the plants that are 8.5 cm or less, we need to add up the widths of all such plants given in the problem statement.
We have the following plant widths: 5.2 cm, 4.3 cm, 9.8 cm, 6.1 cm, 8.4 cm, 7.6 cm, 8.5 cm
To find the total width of plants that are 8.5 cm or less, we need to add the widths of the plants whose widths are less than or equal to 8.5 cm.
Thus, the total width of the plants that are 8.5 cm or less is: 5.2 cm + 4.3 cm + 6.1 cm + 8.4 cm + 7.6 cm + 8.5 cm= 40.1 cm
Therefore, the total width of the plants that are 8.5 cm or less is 40.1 centimeters.
So, option (D) 30 centimeters is incorrect.
Hence, the correct answer is (C) 24.7 centimeters.
