Q1:

The sum of the interior angles of a geometrical figure laid on the surface of the earth differs from that of the corresponding plane figure only to the extent of one second for every

A 100 sq. km of area

B 150 sq. km of area

C 200 sq. km of area

D none of these.

ANS:C - 200 sq. km of area

It is 195.5 km square. So most nearest answer 200 is right.

And for measuring length it's 1cm more in geodic in 12 km. Only one second for every 195.5 ~ 200 km^2.
