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.

1. Calculate the total height:
\( 15 + 18 + 21 + 19 + 20 = 93 \) cm

2. 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**.
