A Rectangle is a plane figure with four straight sides and four right angles, one with unequal adjacent sides, in contrast to a square. Every angle of rectangle is a right angle (900).

Table of Contents:

**Formula**

**Area of Rectangle = **b*h

**Perimeter of Rectangle = **2(b) + 2(h)

**where**,

b = base, h = heigth

**Area of Parallelogram =** b×h

**Perimeter of Parallelogram =** 2(b) + 2(h)

**where,**

b = breadth, h = height

A** rectangle** is defined as a quadrilateral where all four of its angles are right angles.

The opposite sides are parallel and congruent.

The diagonals bisect each other.

The diagonals are congruent.

A **rectangle **is also a **parallelogram.**

**Examples:**

Find the area and perimeter of a rectangle for the breadth 4 and the height 5.

** Step 1:** Find the area.
