1+4+9 = 14 squares.

16 1x1 rectangles + 12 2x1 rectangles + 8 3x1 rectangles + 4 4x1 rectangles + 12 1x2 rectangles + 9 2x2 rectangles + 6 3x2 rectangles + 3 4x2 rectangles + 8 1x3 rectangles + 6 2x3 rectangles + 4 3x3 rectangles + 2 4x3 rectangles + 4 1x4 rectangles + 3 2x4 rectangles + 2 3x4 rectangles + 1 4x4 rectangle. A Grand Total of: 100 squares and rectangles. OR: A rectangle is formed by 2 horizontal lines and 2 vertical lines. There are 5 horizontal and 5 vertical lines so the number of rectangles is 5C2 * 5C2 = 10 * 10 = 100

25 Squares * * * * * 30 squares A 5*5 grid offers squares of sides 4, 3, 2 and 1 - as follows: 1 of 4*4 4 of 3*3 9 of 2*2 16 of 1*1

Infinitely many, but only 30 squares within a 1 unit grid. 4*4 square: 1 3*3 squares: 4 2*2 squares: 9 1*1 squares: 16

If it is 4cm squared (area), then four squares can fit. If it is a square of length and width of 4, 16 squares can fit.

In a grid of A x B squares, the formula to find how many unique rectangles there are (and all squares are considered to be rectangles) is: A * (A+1) * B * ((B+1)/4) A and B are interchangeable. So in a 5 x 4 grid, there are 5 * (5+1) * 4 * ((4+1)/4) Or 5 * 6 * 4 * (5/4) Or 150 unique rectangles. Now if we switch A and B, the equation reads: 4 * (4+1) * 5 * ((5+1)/4) Or 4 * 5 * 5 * (6/4) Again 150 unique rectangles.

If they are 1 x 1 squares there would be 144 in a 12 x 12 grid.

126 rectangles. 1 Strip of 6 equals 21 rectangles, multiply by 1 strip of 3 which makes 6, is 126 rectangles, all in one big rectangle.

7 x 7 = 49 of the smallest squares if there are 7 squares on each side. The total number of "squares" of any size (1 to 49 of the smallest squares) is 140. The number can be calculated from the formula [(n)(n+1)(2n+1)] / 6 where n is the grid size.
