10x10 Squares...
4 white squares and 4 black squares on each row
9 obvious, 3 for each row, 3 for each column, 4 for each rectangle of 4 squares, all of the squares. So 19
There are 8 squares in a row on a checkerboard. The full board consists of 64 squares (8×8).
pyramid with 2 squares on top row, 3 squares on second row, 5 squares on third row, and 7 squars on bottom row
count the top row of squares and multiply that by the number of squares in a coloumn ( which are going down )
Magic squares are grids of numbers that add up to the same number in each row, each column and both long diagonals. ■
A pentomino consists of five connected squares, and if we start with a fixed configuration of 2 squares in a row (let's call it a "domino"), we can add 3 additional squares in various ways. There are 12 unique pentominoes that can be formed from 5 connected squares, but specifically starting with 2 squares in a row, we can create 6 distinct configurations by adding the remaining squares in different orientations. Thus, the number of pentominoes that can be formed with 2 squares in a row is 6.
To find the area of the quilt, you would multiply the number of rows by the number of squares in each row, and then multiply that by the area of each square. So, the area would be calculated as 8 rows x 6 squares/row x (1 foot x 1 foot) = 48 square feet.
2 chance squares...
you press all the squares on the second row once then the 2 in the middle on the third row then all on the last row
The back row of squares on a draughts board is called a crown-head.

If this is for homework, I would state your reasoning for excluding (or including) that set. Count all the options up, and you have 8 different ways you can arrange the rows with the exclusion.
