To calculate the average height of the five plants, you add up all the heights and then divide by the number of plants.
The heights are: 15, 18, 21, 19, 20.
-
Calculate the total height: \( 15 + 18 + 21 + 19 + 20 = 93 \) cm
-
Divide by the number of plants: \( \frac{93}{5} = 18.6 \) cm
So, the final average height for this group of plants is 18.6 cm.
