Explanatory Answer

Method of solving this CAT Question from Geometry

Given that ABCDEF be a regular hexagon with each side of length of 1 cm.
We have to find the area of a square with AC as one side.
ABO is the equilateral triangle with each side having length of 1 cm and ABCO is the rhombus.
Altitude of an equilateral triangle = \\frac{√3}{2}) a
So AP = \\frac{√3}{2}) × 1
Where AP = PC
⟹ AC = AP + PC
⟹ AC = \\frac{√3}{2}) × 2
⟹ AC = √3
Area of a square = a² sq.units
Area of the square with AC as one side = √3 × √3 = 3 sq.units

The question is "Let ABCDEF be a regular hexagon with each side of length 1 cm. The area (in sq cm) of a square with AC as one side is"

Hence, the answer is 3

Choice B is the correct answer
