Look at the square below:
What is its area?
The area of the square is equal to the side of the square raised to the second power.
That is:
Since the drawing gives us one side of the square, and in a square all sides are equal, we will solve the area of the square as follows:

What is the area of the square?
Area measures space inside the shape! When you have a 13×13 square, you're filling it with 13 rows of 13 unit squares each. That's 13 × 13 = 169 total unit squares.
Area = space inside =
Perimeter = distance around =
For this square: Area = 169, Perimeter = 52
Think "side squared" - you're making a square number! The word "square" in math comes from this shape. A 13×13 square gives you 13² = 169.
That's normal for area! Area grows quickly because you're multiplying length × width. Always check: does ? If yes, your answer is correct!
Yes! But try to recognize perfect squares like 13² = 169. Knowing common perfect squares (1², 2², 3²... up to 15²) will make geometry much faster.
