What is a square?

A square can also be defined as a rectangle with all sides equal, a rhombus with all angles equal, or a parallelogram with equal diagonals that bisect each other.

  1. The diagonals of a square bisect each other and meet at 90 degrees
  2. The diagonals of a square bisect its angles.
  3. The diagonals of a square are perpendicular.
  4. Opposite sides of a square are both parallel and equal lengths.
  5. All four angles of a square are equal. (Each is 360°/4 = 90 degrees, so every angle of a square is a right angle.)
  6. The diagonals of a square are equal.

Formula

  • Area of square: [(side)²]
  • Perimeter of square: [4(side)]
  • Diagonal of square: [(side) (sqrt(2))]

How to Calculate the Area, Perimeter, and Diagonal of a Square?

Example

Calculate the Area, Perimeter, and Diagonal of a Square whose length is 10 cm.

Solution:

Apply Formula:

Step1Area of square: [(side)²]

Area of square = 102 = 100

Step 2Perimeter of square: [4(side)]

Perimeter of square=4*10 = 40

Step 3Diagonal of square: [(side) (sqrt(2)) ]

Diagonal of square=10 * sqrt(2) =10*1.41 = 14.1
