The sum of exterior angles for a hexagon is :
A& 0 B) 1440
(೧ 900 യ) 1080

The following perpendicular offsets were taken at 10 m intervals from a survey line
to an irregular boundary line. The area in square metre enclosed between the survey
line, irregular line, first and last offsets by Simpson’s rule is :

(^) 260 m2 (B) 520 m?

(C) 180 m? D) 860 m?
The probable error of area (in m?) of rectangle sides are 100 + — 0.01 m and
200 + - 0.02 0 18 :

(^) +-2 (8) +- 0.0002

(2) + - 0.0 0) 3-147

If the cross sectional areas at every 50 m, in a length of 200 m are :
5 m?2, 10 m2, 15 773, 10 m2, 5 m? then, volume by trapezoidal rule is

(^) 4000 ೫3 (9) 5000 ೫3
(0 2000 ೫3 त) 800005
