Smart Math Formula RectangleSmart Math Formula Rectangle, The rectangleis defined as aquadrilateral where all fourangles are right angles. Ithas two pairs of parallel sides.

b = breadth, l = length
A = Area, P = Perimeter  

If that is the area declared and asked to find, length or breadth of the formula is as below: 
Area of Rectangle       = l . b
length of Rectangle     = A : b
breadth of Rectangle   = A : l

If that is the perimeter declared and asked to find, length or breadth of the formula isas below:  
Perimeter of Rectangle = 2 [ l + b ]
length of Rectangle       = P : 2 - b
breadth of Rectangle     = P : 2 - l
      

Example


Question : Find the area and perimeter of a rectangle for the breadth 5 and the length 20.

  Question : Find the area.
            Area = l . b = 20 . 5 = 100

  Question : Find the perimeter.
            Perimeter = 2 [l + b] = 2 [20 + 5] = 50.


Rectangle the perimeter declared
Question : Find the length and breadth of a rectangle for the perimeter 32, breadth 6

Question : Find the length. 
length = P : 2 - b = 32 : 2 - 6 = 10
  
  
The above example will clearly illustrates how to calculate the Area and Perimeter of a Rectangle manually, so you will be Smart Math Formula Rectangle.
