surface area of earth which is land
= (1/4)4πr^2
= π(6370)^2
= 127,476,091 km^2

If 3/4 th part is covered by water , remaining part will pe area of land I.e. 1-3/4= 1/4 th part
Radius given=6370 ,
Area is sphere= 4πr^2
1/4(4*22/7*6370*6370)
After solving we will get the ans as -- 127527400 km^2
Hope helped !
