A rectangle is a quadrilateral where every angle is right angle (90⁰). It can also be said an **equiangular** quadrilateral as equiangular means that all the angles are equal.

*360⁰/4 = 90⁰*

## Properties of Rectangle

- Each internal angle is 90⁰.
- Opposite sides are equal.
- Opposite sides are parallel.

## Area of Rectangle

Area of rectangle is the multiplication of the length and width of the rectangle.

*A= L x W*

## Parameter of Rectangle

The parameter of the rectangle is twice the times of sum of length and width of rectangle.

*P= 2(L + W)*

## Diagonals of Rectangle

Diagonals of rectangle are equal in length and intersect in the middle. There are 2 diagonals in a rectangle.

*Diagonal(d)= **√(W² + L²)*
