Absolute value of 36 is 36; Wo, we have:



361 congruent square tiles would be needed to cover the square shaped floor.
<h3>Equation</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Since the number of tiles lying on both diagonals is 37. Let x represent the number of tiles on each side.
Counting one tile twice, there are:
- 37=2x-1
- x=19 tiles on each side.
19² = 361
361 congruent square tiles would be needed to cover the square shaped floor.

Let x be the number of base hits Ricky got. With this representation, the number of base hits Pedro got is x + 277. The sum of their number of hits is equal to 2685. The equation that best represent the scenario is,
x + x + 277 = 2685
The value of x is 1204. Therefore, Ricky got 1204 and Pedro got 1481.
