Single line 4.9m width.

Double. 6 m.
So, 4.9 /6 = 0.82.
Answer C.

L1 = xcos30°.
L2 = xcos60°.

L1/L2 = 1.732 = approximately equal to 2.

30°- 4.66 m. & 60°=5.58m.
So, ratio=(4.66/5.58)==0.8.

(5sin30+2.5sin30)/(5sin60+2.5sin60) =.577 ==.5 = A.

[Lsin60° +l/2sin30°]/[Lsin30° + l/2sin60°].
(L=6).

= [6sin60°+3sin30°]/[6sin30°+3sin60°],
= [6.206/7.281].
= 0.85 Ans.
