Rectangle

A rectangle is a four-sided flat shape (a quadrilateral) where every interior angle is a right angle ($90^\circ$). Opposite sides of a rectangle are parallel and equal in length.

Example

For a rectangle with a length of $8 \text{ cm}$ and a width of $3 \text{ cm}$, the area is calculated as $Area = 8 \times 3 = 24 \text{ cm}^2$.
