Answer:
Step-by-step explanation:
To determine the final height of the grass, we need to convert the measurements to the same unit. We can convert 0.5 meters to centimeters by multiplying it by 100 (since there are 100 centimeters in a meter):
0.5 meters * 100 centimeters/meter = 50 centimeters
Now, we can add the additional growth of 9 centimeters to the current height of 50 centimeters:
50 centimeters + 9 centimeters = 59 centimeters
Therefore, if the grass on your lawn grows another 9 centimeters, it will be 59 centimeters high.
