### What is Meant by Square?

In mathematics, a square is a closed two-dimensional shape with four sides. All the sides of the square are of equal measure. Since the square has four sides, the square is called the quadrilateral. A square is considered as a polygon, in which the interior angles add up to 360 degrees. All the interior angles are of equal measures, and each angle measures 90 degrees (right angles). The area of the square is the region occupied by the square, and the perimeter is the sum of four sides of the square. The formula to calculate the area and the perimeter of a square is given by:

Area of a square = a^{2} square units

The perimeter of a square = 4a units

Where “a” is the side length of a square
