Calculating the Height of the Tree

To calculate the height of the tree in the given scenario, we can use the information provided. The tree's height in spring was 7 dm, and it grew by 20 cm over the summer.

1 decimeter (dm) = 10 centimeters (cm)

So, the initial height of the tree in centimeters was 7 dm * 10 cm/dm = 70 cm.

The tree then grew by 20 cm, resulting in a final height of 70 cm + 20 cm = 90 cm by autumn.

Therefore, the height of the tree by autumn was 90 cm.
