To find the area and perimeter of a square, you need to use simple formulas that relate to the square’s side length.
Area of a Square
The area of a square is calculated by taking the length of one side and squaring it. The formula is:
Area = side × side or Area = side²
For example, if the length of each side of the square is 4 units, the area would be:
Area = 4 × 4 = 16 square units
Perimeter of a Square
The perimeter of a square, which is the total distance around the square, is found by adding up all four sides. Since all sides of a square are equal, the formula is:
Perimeter = 4 × side
For the same square with a side length of 4 units, the perimeter would be:
Perimeter = 4 × 4 = 16 units
In summary, to find the area, use the side length squared, and to find the perimeter, multiply the side length by 4. These calculations are straightforward and can easily be applied to any square.
