The area of a square sticky note is 9 square inches. What's the side length of the sticky note?(1 point)
inches
The side length of the sticky note is 3 inches.
To find the side length of a square sticky note, we can use the formula for the area of a square, which is side length squared.
Given that the area of the square sticky note is 9 square inches, we can use the formula to find the side length.
Let's assume the side length of the sticky note is "x" inches.
According to the formula, the area of the square is equal to x squared.
Therefore, we solve the equation x^2 = 9.
To find the value of x, we take the square root of both sides of the equation:
√(x^2) = √9
This simplifies to:
x = 3
Therefore, the side length of the sticky note is 3 inches.
To find the side length of the square sticky note, you can take the square root of the area.
First, let's set up the formula:
Area of a square = side length × side length
Given that the area is 9 square inches, we can substitute this value into the formula:
9 = side length × side length
Next, take the square root of both sides to isolate the side length:
√9 = √(side length × side length)
Simplifying, we get:
3 = side length
Therefore, the side length of the sticky note is 3 inches.
