## âœ…What is Rectangle?

A rectangle is a type of quadrilateral, whose opposite sides are equal and parallel. It is a four-sided polygon that has four angles, equal to 90 degrees. A rectangle is a two-dimensional shape.

Here are some important formulas related to Rectangle:

## Perimeter of a Rectangle:

**ðŸ‘‰Formula**: P = 2 * (l + w)

Where l is a length and w is the width of rectangle.

**ðŸ‘‰Example**: If the rectangle has a length is 3 and width is 4, then the perimeter would be P = 2 * (l + w) = 14 cm.

## Area of a Rectangle:

**ðŸ‘‰Formula**: A = l * w

Where l is a length and w is the width of rectangle.

**ðŸ‘‰Example**: If the rectangle has a length is 3 and width is 4, then the perimeter would be A = l * w = 12 cm.

These formulas can be used to find the area and perimeter of any rectangle.
