The area of the the base of a square notepad is 9 square inches. What is the length of one side of the base of the notepad?
+1667 We know the formula of the area of a square is length * width.
If the area is 9, that means l * w = 9.
The notebook is square, which means all sides are equal.
We can conclude that length = width.
That means w^2 = 9.
(Note: I am using width for this example, but you can also use length.)
This can be changed to the square root of 9 = w.
The square root of 9 is 3, therefore w = 3.
Length and width are equal, which means every side must have a length of...
