## What is Rectangle?

A rectangle is a 2D shape in geometry, having 4 sides and 4 corners. Its two sides meet at right angles. Thus, a rectangle has 4 angles, each measuring 90 ̊. The opposite sides of a rectangle have the same lengths and are parallel. Two sides are said to be parallel, when the distance between them remains the same at all points.

Since all the angles of a rectangle are equal, we also call it an equiangular quadrilateral. Parallelogram ## Properties of a rectangle:

It is a flat shape

It has 4 sides (edges)

It has 4 corners (vertices)

It has 4 right angles

## Area of a rectangle:

The area of a rectangle is the product of its two adjacent sides Area of a rectangle = Length × Width

Perimeter:

The perimeter of a rectangle is the sum of the length of its four sides. Since parallel sides of a rectangle have the same length, the formula for the perimeter of a rectangle is

Perimeter of a rectangle = Length + Width +Length + Width

=2 length +2Width

=2 (length +Width)

Diagonals of a rectangle:

The line segments that join the opposite corners of a rectangle are called its diagonals. In the given figure, the two diagonals of the rectangle are AC and BD. The diagonals of a rectangle are the same in length.

Therefore, AC = BD Rectangle being the most common shape forms a part of our day to day life. Some real-life examples of the rectangle are table tops, books, mobile phones, TV, etc. Fun FactsAll rectangles are parallelograms, but all parallelograms are not rectanglesThe diagonals of a rectangle divide the rectangle into four triangles .tags a { color: #fff; background: #909295; padding: 3px 10px; border-radius: 10px; font-size: 13px; line-height: 30px; white-space: nowrap; } .tags a:hover { background: #818182; } Home Contact - Advertising Copyright © 2021 positiveeast.org #footer {font-size: 14px;background: #ffffff;padding: 10px;text-align: center;} #footer a {color: #2c2b2b;margin-right: 10px;}
