Answer: The forest received 522.29 cm rain in three years.
Explanation:
Given : Rain received by Australian rainforest in first year = 201.25 cm
Rain received by Australian rainforest in second year = 158.11 cm
Rain received by Australian rainforest in third year = 162.93 cm
Now , the total rain received by the forest receive in the three years = (Rain received in first year)+ (Rain received in second year)+(Rain received in third year)
= 201.25 + 158.11 + 162.93 cm
= 522.29 cm
Hence, the forest received 522.29 cm rain in three years.
