dreptunghiului

Dreptunghiul is a geometric shape, a quadrilateral with four right angles. This means that all interior angles measure 90 degrees. In a dreptunghi, opposite sides are parallel and equal in length.

The area of a dreptunghi is calculated by multiplying its length by its width. The formula is Area = length × width. The perimeter of a dreptunghi is the sum of the lengths of all its sides, or twice the sum of its length and width. The formula is Perimeter = 2 × (length + width).

A special case of a dreptunghi is a square, where all four sides are of equal length. In this case, the area is side × side, and the perimeter is 4 × side.

Dreptunghiuri are fundamental shapes in geometry and appear frequently in architecture, design, and everyday objects. They are easily recognizable due to their four equal angles and parallel opposite sides. Properties such as symmetry and congruence are also important characteristics of dreptunghiuri. The diagonals of a dreptunghi are equal in length and bisect each other, meaning they intersect at their midpoints.
