MENSURATION: SQUARE

MENSURATION: SQUARE


In mathematics, a square represents a closed geometrical shape which has four equal sides and four right angles, the right angle means 90 degrees.

Properties of Square
  1. l is the side length the square
  2. d is the diagonal of the square
  3. All internal angle is 90 degree
  4. All side are equal

Important Formula for Square

Area Of Square (A)

Area(A) = Side(l) X Side(l)
Example: Calculate the area of a square whose side is 4cm
Given: Side(l) = 4cm
Formula:
           Area(A) = Side(l) X Side(l)
           Area(A) = 4cm X 4cm
          Area(A) = 16 cm^2
Area of given square is 16 cm^2

Perimeter of Square(P)

Perimeter(P) = 4 x Side(l)
Example: Calculate the perimeter of a square whose side is 4cm
Given: Side(l) = 4cm
Formula:
            Perimeter(P) = 4 x Side(l)
            Perimeter(P) = 4 x 4cm
            Perimeter(P) = 16 cm  
The perimeter of the given square is 16 cm

Diagonal of Square(D)

Diagonal(D) = Sqrt(2) x Side(l)
Example: Calculate the diagonal of a square whose side is 4cm
Given: Side(l) = 4cm
Formula:
           Diagonal(D) = Sqrt(2) x Side(l)
            Diagonal(D) = Sqrt(2) x 4cm
            Diagonal(D) =  1.414 x 4cm
            Diagonal(D) = 5.656 cm
Diagonal of given square is 5.656 cm
