Can be calculated theoretically) So, area of the smallest square $$= \frac{8}{2} = 4$$ Side of the smallest square $$= \sqrt{4} = 2$$ _________________ Kindly press "+1 Kudos" to appreciate EMPOWERgmat Instructor Status: GMAT Assassin/Co-Founder Affiliations: EMPOWERgmat Joined: 19 Dec 2014 Posts: 13325 Location: United States (CA) GMAT 1: 800 Q51 V49 GRE 1: Q170 V170 Re: In the figure above every square is contained (inscribed) [#permalink] Show Tags 08 Jan 2015, 13:26 Hi All, This is a great "concept" question and can be solved without a lot of complex math. You do need to understand how the squares relate to one another though.... **Note: For organizational purposes, I'm going to refer to the 3 squares as the 'large', 'medium' and 'small' squares.** To start, we know that the area of the large square is 16, so each of its sides = 4. If you take the 4 corners of the large square and "fold them in" so that they meet at the center, you will end up with a square with the same size as the medium square. This means that the medium square has the same area as the sum of the 4 white-corner triangles: medium square = 4 white triangles medium square + 4 white triangles = large square = area of 16 medium square = 4 white triangles = area of 8 This medium square has an area of 8, so its sides are each 2(root2). Now we can do the same "math moves" (as above) with the medium square and the small square... Fold the 4 black triangles of the medium square towards the center and you get a square with the same size as the small square. small square = 4 black triangles small square + 4 black triangles = medium triangle = area of 8 small square = 4 black triangles = area of 4 So, the small square has an area of 4, so its sides are each 2.

Smallest square's side is about half of the largest one, so 4/2=2

Paresh, thanks for concept
