The area of a square is the amount of space contained within its four equal sides. To find the area, you simply multiply the length of one side by itself. For example, if each side of the square is 4 units long, the area would be 4 x 4, which equals 16 square units. This measurement helps us understand how much space is available inside the square. Understanding the area of a square is useful in many real-life situations, such as when planning a garden or laying out a room. Knowing the area allows you to determine how much soil, grass, or flooring you will need, making it an essential concept in both math and everyday life.
