Smart Math Formula Rectangle, The rectangle is defined as a quadrilateral
where all four
angles are right
angles. It has 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 is as below:
Perimeter of Rectangle = 2 [ l + b ]
length of Rectangle = P : 2 - b
breadth of Rectangle = P : 2 - l
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 is as below:
Perimeter of Rectangle = 2 [ l + b ]
length of Rectangle = P : 2 - b
breadth of Rectangle = P : 2 - l
Example
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.
