Rectangle
Has 4 right angles
A rectangle is a geometric shape that has four straight sides, with right angles at each of the corners. It is a type of parallelogram with two pairs of parallel sides that are equal in length. The opposite sides of a rectangle are equal in length and parallel to each other, and the diagonals of a rectangle bisect each other at right angles.
The area of a rectangle is the product of its length and width, which is expressed as A = l x w, where A is the area, l is the length and w is the width. For example, if a rectangle has a length of 5 meters and a width of 3 meters, then its area would be 15 square meters.
The perimeter of a rectangle is the sum of the lengths of all its sides, which is expressed as P = 2l + 2w, where P is the perimeter, l is the length and w is the width. For example, if a rectangle has a length of 5 meters and a width of 3 meters, then its perimeter would be 16 meters (2(5) + 2(3)).
Rectangles are commonly found in everyday objects, such as windows, doors, and computer screens. They are also used in many mathematical and engineering applications due to their simple and predictable properties.
