Quantitative Aptitude - Geometry - Polygons - Let ABCDEF be a regular hexagon Quantitative Aptitude - Geometry - Polygons Question 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 A) 3√2 B) 3 C) 4 D) √3 Answer Option (B) Solution From CAT 2017 - Quantitative Aptitude - Geometry - Polygons, we can see that, Angle (ABC) = 120 deg According to the formula, Cos (theta) = (b^2 + c^2 – a^2)/2bc Cos (120) = [(AB)^2 + (BC)^2 – (AC)^2]/2*AB*BC
