Givens:

• In July, the plant was 64.34 centimeters tall.
• In August, the plant grew 18.2 centimeters.

So, by the end of August, the height of the plant would be the sum of the height in July plus the centimeters it grew in August. The exact value would be

`64.34+18.2=82.54`

Therefore, by the end of August, the plant was 82.54 centimeters tall.
