# A square within a square...

Geometry Level 3

Let ABCD be a square. An equilateral triangle is placed on each side of the square, such that the base covers the whole side. Now join up the $${exposed}$$ corners of the equilateral triangles (only join $${adjacent}$$ corners) such that a larger square, PQRS, is formed. What is the value of $$\frac{area of PQRS}{area of ABCD}$$? ( give your answer to 2dp)
