The solution approach uses the SQL SELECT statement to calculate the distance. It first finds the maximum and minimum values of latitude and longitude. It then uses the Pythagorean theorem (expressed as SQRT(POWER(MAX(LAT_N)-MIN(LAT_N),2)+POWER(MAX(LONG_W)-MIN(LONG_W),2))) to calculate the distance between these extreme points. The result is rounded to four decimal places using the ROUND function.
SELECT ROUND(SQRT(POWER(MAX(LAT_N)-MIN(LAT_N),2)+POWER(MAX(LONG_W)-MIN(LONG_W),2)),4)
