# How many types of Rectangle?

A **rectangle** is a **polygon** with **four sides** ( quadrilateral ) equal to two to two. In addition, its four **interior angles** are **right angles** (90º). In this post, you will be able to learn about Types of Rectangle with properties, the formula to find the Area of Rectangle, and the Perimeter of Rectangle with Examples.

### Parts of Rectangle

**Sides**: It has four sides, each side being equal to its opposite (*a*and*b*), that is, two to two.**Angles**: its four angles (α) are equal and straight 90º (π/2 radians). The interior angles, as in all quadrilaterals, add up to 360º (2π radians).**Diagonals**– Diagonals are segments joining opposite vertices. It has two equal diagonals (*D*and_{1}*D*) that intersect at the center of the rectangle._{2}**Axes of symmetry**: they are imaginary lines that divide the rectangle into two symmetrical parts with respect to said axis. It has two axes of symmetry (*E*,_{1}*E*) parallel to sides_{2}*a*and*b*and passing through the center of the rectangle.

### How to find Area of Rectangle?

The **area of the rectangle** is calculated from the two different sides ( *a* and *b* ). It is the product of the two contiguous sides of the rectangle.

Area of Rectangle = Length of Rectangle x Width of Rectangle

X = a x b

Where “a” and “b” are the length and width respectively.

**Example:**

Let be a **rectangle** whose sides are equal two to two in length *a* = 3 cm and *b* = 5 cm.

The **area** of the rectangle will be the product of the two different sides, that is:

X = 3cm x 5cm

X = 15 cm. cm

### Formula to Perimeter of Rectangle

The perimeter of a rectangle can be found by the following formula:

Perimeter of Rectangle= 2(Length + Breadth)

Y = 2 ( x + y )

where “x” and “y” are the length and breadth of the Rectangle.

### Rectangle Properties?

- The opposing sides are equal and parallel.
- Each angle on the inside is a right angle.
- The diagonals are equal in length and bisect each other.
