How u get 15
To find the length of one side of a square when you know its area, you can use the formula:
Area of a square = side length * side length
Given that the area of the square is 225 cm², you can substitute this value into the formula:
225 cm² = side length * side length
To solve for the side length, you need to take the square root of both sides of the equation. The square root of a number is the value that, when multiplied by itself, gives the original number.
√(225 cm²) = √(side length * side length)
The square root of 225 cm² is 15 cm since 15 × 15 = 225. Therefore, the length of one side of the square is 15 cm.
