Answer:
The field losses a total of 55.814 litres of water in an hour.
Explanation:
As the complete question is not given here, the average rate of water loss is not given here which is found in normal conditions as 1.67 mL/m2.
Now the average rate of water loss per minute is 1.67 mL/m2
So the average rate of water loss per minute for 557 m2 is 1.67*557=930.19 mL
So 930.19 mL of water is lost from the field in 1 minute, for the calculation of water lost in an hour, the value is given as 60*930.19 =55811.4 mL or 55.814 litres.
