Perimeter of a square
Formula: a * 4 = U (circumference)
Example calculation: 5cm * 4 = 20cm
Area of a square
Formula: a * a = A (area)
Examplecalculation: 5cm * 5cm = 25cm2
The calculation of a square can refer to different aspects, including the calculation of the area, the perimeter or the diagonals. Here are the basic formulas for these calculations:
- The area of a square: the area of a square is calculated by squaring the length of a side. So if the length of a side is a, then the area is A = a².
- The perimeter of a square: The perimeter of a square is calculated by multiplying the length of a side by four. So if the length of a side is a, then the perimeter is P = 4a.
- The diagonal of a square: The diagonal of a square is calculated by multiplying the length of one side by the square root of two. So if the length of a side is a, then the length of the diagonal is d = a√2.
These formulas apply regardless of the size of the square and can be used to calculate various properties of a square, provided the length of a side is known.
