Since 1978 it is known that the minimal number of pieces in a perfect tiling of a square with squares is 21. ABSTRACT. Finally we use these results to calculate the homotopy type of some spaces of tilings.Let Tn denote For example the square \require{enclose}\enclose{horizontalstrike}{343×343}, its binary representation is 101010111.2N_l+2N_w-4+(Z_l+1)(Z_w+1)\lt N_lN_w$$Thus a square cannot be tiled with nitely many rectan-gles similar to a 1 p 2 rectangle. The program must show all the ways in which these copies can be arranged in a grid so that no two copies can touch each other. So this means the 30×30 square requires the same number of base-2 rectangles as the 15×15 square. On one hand, this has strictly smaller height, so we have, by induction and our definition of k:$$\sum_i \lambda(T_i') \leq r(R_0)-k$$.

The formula for the total number of base-2 rectangle used is $2f\left(\frac{m+a}{2}\right) I think your original claim is false.I don't know how to send a picture in comment but you can easily draw$3\times 4$counter examples(two horizontal dominos and two vertical dominos in first two rows and two$1\times1$square and a domino on the third row).the problem is on your induction step the rectangles above two removed rectangle may not be distinict. I colored a few squares to simplify my explanation of my process. Note that 'perimeter' tiles have smaller or larger area than 'area' tiles. Notice that numbers in the board range from 1 to 52 with no repetitions. :). My method uses less rectangles than the op when $$2f\left(\frac{m+a}{2}\right) f\left(\frac{n-b}{2}\right)+2f\left(\frac{m-a}{2}\right) f\left(\frac{n+b}{2}\right)+f(a)f(b)\lt f(m)f(n)$$, $$f\left(\frac{m+a}{2}\right)=1$$ 5&5&5&5&5&5&5&5&A&A&A&A&8&B&B&B&B&B&B&B&B&9&9\\ The binary representation of 1927 is 11110000111. 29 is forced into the horizontal position, in turn forcing 23 horizontal and making 8 the perimeter of a 1x3 block. In particular, a square can be tiled by rectangles of ratios 2+ p 2 and 1 2+ p 2 but cannot be tiled by rectangles of ratios 1+ p 2 and 1 1+ p 2; see  for an elementary proof. 4 cannot be taller than 1 block, because then the corner between 9 and 12 cannot be filled without blocking the corner between 12 and the edge. This is the best place to expand your knowledge and get prepared for your next interview. Tiling a unit square with rectangles of area$\frac 1k \times \frac{1}{k+1}$but not with those side lengths - any references (Web, book, etc.)? MathJax reference. Some helpful logic (maybe). So you have some leeway, but not too much as you have to make up that 831 in area.
