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 the space inside the square. Think of it as counting unit squares: 11 rows with 11 squares each = 11 × 11 = 121 total unit squares!
Perimeter is the distance around the outside (11 + 11 + 11 + 11 = 44). Area is the space inside the shape (11 × 11 = 121).
Think "A square has equal sides, so area equals side squared!" The formula means multiply the length by itself.
Yes! 121 is . Perfect squares come from multiplying whole numbers by themselves: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121...
The same formula works! If the side was 11.5, the area would be . Just multiply the decimal by itself.
