Question

If 100 buttons are arranged in a square form then each row contains 9 buttons true or false

Answer 1

The area of a square is given by the product of two sides(since they're equal, the square of a side). Since we have to arrange 100 buttons in a square, each column and row are going to have the same amount of buttons, and this amount is given by the square root of 100.

`\sqrt[]{100}=10`

Since the square root of 100 is 10, each row of this square have 10 buttons, therefore, the affirmative saying it has 9 is false.
