Question
ABC is an equilateral triangle and AX,BY and CZ are three parallel lines. Find the area of triangle ABC
Options:
A .  a2+b2−ab√3
B .  a2+b2+ab√3
C .  a2+b2√3
D .  a2−b2√3
E .  B at 1pm
Answer: Option B

There is no constraint given, other than that ABC is an equilateral triangle and AX || BY || CZ.
We can therefore assume that X,Y and Z are points on the side AC itself. If we assume the equilateral triangle to have a side=2, and the Y is the mid point of AC, then AY=YB=1
Area of the triangle = 34 a2 = 3
Look in the answer options and eliminate those options where you do not get √3 on substituting a=1 and b=1.
Answer is option (b)
