Perimeter of a Rectangle Formula
Perimeter of a Rectangle Formula
In mathematics, we can define the Geometry as a col ection of various types of geometrical
figure and shapes which is used for completing the various types of tasks, which are related to
the concepts of mathematics.
In the Euclidean geometry, a rectangle can be considered as a quadrilateral that contains the
four right angles. In the mathematical term, the rectangle can be cal ed as equiangular
quadrilateral.
It can also be defined as a parallelogram that contains four right angles. The Rectangle word
comes from the Latin word `rectangulas' which is a combination of two words `rectus' and
`angulus'.
The word `rectus' refers to right and the `angulus' refers to angle.
In the mathematical terms we can define the rectangle as the geometrical shape which looks
similar to the shape of square. It is most commonly known as quadrilateral.
It is also defined as the shape of geometry with the four interior angles of 90degree. In the
Rectangular shape all the opposite sides are similar to each other.

Here in the below we show you some of the properties of rectangle that helps in
understanding the concept of rectangle:
(a ) All the Opposite sides of the rectangle are congruent and paral el to each other.
(b ) The diagonals of the rectangular shape are bisecting to each other.
(c ) The diagonals of the rectangles are intersecting at the central point of the rectangle.
Here we are going to discussing about the perimeter of the rectangle formula. First of al we
are going to discussing about the perimeter of the rectangle.
The perimeter of the rectangle can be defined as a distance around the outside the shape of
the rectangle. As we describe that the shape of rectangle contains four equal sides that have
two pair of opposite sides that are equal to each other.
It means to say that in the rectangle paral el sides are equal to each other. A rectangle has
four sides with opposite sides that are being congruent.
To calculate the perimeter of the rectangle, we need to add the value of al four sides. The
formula for calculating the perimeter of the rectangle can be calculated by adding al the pairs
of the rectangle that are equal to each other.
In the below we show you the formula for calculating the perimeter of the rectangle:
Perimeter of a Rectangle Formula is: 2 * (length + breathe)
The above notation shows that addition of the length and breathes of the rectangle and after
that multiplies the resulted addition with the two.
Now we show you some of the example that helps in understanding the formula for calculating
the perimeter of the rectangle:

Example: Suppose Harry has a piece of land and he wants to develop a boundary around the
land. The land is in shape of rectangle that has length of 5 meter and the value of breathe is 4
meter.
The cost for developing a boundary is $3 @ per meter. Now we need to calculate the total
cost of developing a boundary?
Solution: In the above given question the length of rectangle is = 5 meter
The breathe of the rectangle is = 3 meter
So, the perimeter of the rectangular land is = 2 * (length + breathe)
= 2 * (5 + 3 )
= 16 meter
Now, the total cost of developing a boundary is = 16 * $ 3 = $ 48
