Answer:
Growth of coral reef in meters = 0.0202 m= 2.02 x 10⁻²m
Step-by-step explanation:
1 meter = 100 cm
1 cm = 10 millimeter
1 meter = 100 x 10 = 1000 millimeter.
1 millimeter = 1/1000 = 0.001 meter.
A coral reef grew 20.2mm taller = 20.2 x 0.001 m
= 0.0202 m
Growth of coral reef in meters = 0.0202 m= 2.02 x 10⁻²m
