The total number of squares in a square grid of side 4 =30. ⇒ 16 small squares, 9 3×3 squares, 4 2×2 squares and 1 4×4 square. 1×1 :-1^2 = 1. 2×2 :- 2^2 + 1^2 = 5.
How many squares are needed to cover one edge?
Since the final square has size less than 11, this can only happen for one edge. We may suppose the size a and d squares leave a gap, so a + b = c + d = 11 and b + c = 13. Thus b = 11 − a, c = a + 2, d = 9 − a.
What is the fewest number of squares required to cover a…?
The remaining possiblility is 2 2 + 5 2 + 5 2 + 5 2 + 8 2, but it’s easy to see that an 8 × 8 square and three 5 × 5 squares won’t fit in the rectangle. EDIT: There’s no tiling of the 11 × 13 rectangle with 5 squares even if you don’t require integer sides. It’s best to work up to 5 tiles one at a time.

How to create flexible square grid with CSS grid layout?
I was struggling with creating flexible full-viewport-width square grid defined by the the square size (if you want fixed number of columns it’s much easier to go with vw units).
What happens when you add three rows to a square?
If there are three rows, adding an extra column allows us to make 3 more squares, more squares and more square. This is a total of squares.
Is it possible to make a rectangle with 3 rows?
This tells us that it isn’t possible to make a rectangle with squares which has rows. If there are three rows, adding an extra column allows us to make 3 more squares, more squares and more square. This is a total of squares. This gives us the sequence which tells us that we can’t make a rectangle with exactly squares which has rows.
