What is Square

A square is a rectangle with four equal sides and four right angles. A square is a special case in geometry that is both a rectangle and a rhombus. Squares are important in many fields, including art, architecture, and math. Squares are also important in many games, including chess, checkers, and hopscotch.

The square has equal sides and equal angles, making it a very simple shape compared to the other shapes. Squares are used to build houses, roads, furniture, and other objects. Squares are often found in nature.

Square formula:-

  • Area of square = (side)² = a²
  • Diagonal of square = √2 x side = a√2
  • Perimeter of square = 4 x side = 4a meter

How to solve the Square problem

Example.1:-Square side length = 20 cm, find area of Square, Perimeter of Square and Diagonal of Square.

Area of square = (side)² = (20)² = 400 cm²

Diagonal of square = √2 x side = √2 x 20 = 28.284 cm

Perimeter of square = 4 x side = 4 x 20 = 80 cm
