Answer 2

Answer:

11-n also ranges from 1 to 10, but in the other direction. So, provided I didn't make a calculating error, the solution is the sum of the squares from 12 to 102, which is 285 in this case.

Step-by-step explanation:

Step : 1  For instance, if a 10 10 grid has 18 shaded squares, then the proportion of shaded squares in the grid is 18%. There is a formula for this, which I had to look up, but the sum of the first n squared results in 10x11x21/6=5x11x7=385 squares overall. We must divide the value by the entire value to find the percentage, and then multiply the resulting number by 100.

Step : 2 In a n x n grid, the total number of grid squares and tilted squares, is equal to the number of tilted squares in a (n+1)×(n+1) grid.These figures ultimately turn out to be square numbers: 64, 49, 36, 25, 16, 9, 4, 1. These total 204 when combined together. Because you sum all the square numbers from 1 to 10, the answer for a larger chessboard, such as a 10 by 10 board, would be 385.

Step : 3 Put your ruler at the top of the page and make a tiny mark every inch to create this grid. Then, repeat the process with the ruler positioned at the bottom of the page. Next, draw a straight line linking each dot at the bottom to its mate at the top using the ruler.
