### What is Rectangle?

Rectangle is most commonly known quadrilaterals whose all interior angles(each 90 ) & opposite sides are equal.Here, you will learn Area of Rectangle & its Properties.

### Area of Rectangle

Area = width × height

Area of Rectangle = w x h square units.

Where,
“w” is the width
“h” is the height

### Perimeter of Rectangle

The perimeter of a rectangle is found by adding all the sides.

Perimeter = w + h + w + h
=2w + 2h
=2(w + h)

P = 2 x (width + height) units

Where,
“w” is the width
“h” is the height

### Diagonals of a Rectangle The diagonals of the square divide the rectangle into two equal right angle triangle.
The length of Diagonal of a rectangle can be found by using pythagorus theorem in the anyone of the right-angle triangle formed by diagonal.you will find given formula of the length of diagonal of the rectangle.

Hypotenuse2 = Perpendicular2 + Base2 (Pythagorus theorem)
Diagonal = √(width squared + height squared):

d = √(w2 + h2)
Where,
“d” is the diagonal

### Properties of Rectangle

• The opposite sides of a rectangle are parallel. (AB || CD).
• The opposite sides of a rectangle are equal. (AB = CD & BC = AD).
• Each of the interior angles of a rectangle is 90°
• The diagonals of a rectangle bisect each other.
• The sum of the interior angles of the rectangle is equal to 360 degrees. i.e.,

∠A + ∠B + ∠C + ∠D = 360°
