Ristkülikukujulist

Ristkülikukujulist refers to a rectangular shape. In geometry, a rectangle is a quadrilateral with four right angles. This means that all four internal angles measure 90 degrees. Opposite sides of a rectangle are parallel and equal in length.

The area of a rectangle is calculated by multiplying its length by its width. The perimeter of a rectangle is the sum of all its sides, which can be expressed as twice the sum of its length and width.

Rectangles are fundamental shapes in geometry and appear frequently in everyday life. They are used in architecture for doors, windows, and buildings. In art and design, rectangles form the basis of many compositions. Many objects we encounter daily, such as books, screens, and fields, are rectangular in shape. The properties of rectangles, such as their parallel sides and right angles, make them easy to measure and construct, contributing to their widespread use.
