Answer: it grew by 240 mm
Step-by-step explanation:
When she planted the tree in April, the height was 33 cm. We would convert centimeters to millimeters.
1 cm = 10 mm
33 cm = 33 × 10 = 330 mm
By the end of July, the height of the tree was 0.57 meters. We would convert meters to millimeters.
1 m = 1000 mm
0.57 m = 0.57 × 1000 = 570 mm
Therefore, the height in mm that the cherry tree grew between April and July is
570 - 330 = 240 mm
