What is the area of the square?
The area of the square is equal to the side of the square raised to the second power.
That is:
Since the diagram provides us with one side of the square, and in a square all sides are equal, we will solve the area of the square as follows:
Look at the square below:
What is the area of the square?
Area measures space inside the shape, not distance around it. Think of it as counting unit squares: you need 3 rows of 3 squares each, so 3 × 3 = 9 total squares!
Perimeter is the distance around the outside (3 + 3 + 3 + 3 = 12). Area is the space inside (3 × 3 = 9). Area uses square units like cm², while perimeter uses regular units like cm.
Yes! The formula works for any square, no matter what the side length is. If the side is 5, area is 25. If the side is 10, area is 100.
Imagine filling the square with unit squares (1×1 squares). You can fit 3 unit squares along each side, creating a 3 by 3 grid with 9 total unit squares inside!
The same formula works! For example, if the side is 2.5, then . Just remember to square whatever number represents the side length.
