There is a formula for the "difference of squares." In this case, the answer is (x + 10)(x - 10)
Ten columns and ten rows, forming 100 squares.
Well, isn't that just a happy little problem to solve! If you have 25 squares in total and 10 of them are shaded, you can find the percentage by dividing the number of shaded squares by the total number of squares, then multiplying by 100. So, 10 divided by 25 equals 0.4, and when you multiply that by 100, you get 40%. Just like that, you've turned a blank canvas into a beautiful calculation!
3/10 are shaded.
5 of 10 shaded would be 1/2 or 0.5 of the total number of squares.
It is: 5/20 times 100 = 25% shaded squares
Think of the following 'sketch' as your 40 boxes... Each X represents one box. Each O represents a shaded box. XXXXXXXXOO XXXXXXXXOO XXXXXXXXXX XXXXXXXXXX
3 shaded blocks out of 10 is 3/10, or .3

We start wit 102 squares. Then we divide 102 by 10 and leave the remainder intact. 102/10=10R2. The Remainder is two.
The fraction of shaded areas is 5/10 = 5 ÷ 10 = 0.5
