yah java varg apane trigya ko dekhte hue ek vrutt kii paridhi or trigya ko paata he.trigya ko dabl data prakaar ke rup main fnction main kodit kiya jaataa he.is kodit trigya ko anya ready ke saath halkon ke paridhi or kshetra ko khojane ke liye badla ja saktaa he.

9.6 ke pradaan kiye gaye trigya ke saath, is kaarykram kaa utpaadan he
paridhi he = 60.31857894892403
kshetra he = 289.52917895483534
