## Introduction

Shapes play a crucial role in mathematics and geometry. Understanding the properties of different shapes helps us solve various problems and visualize concepts. In this article, we will delve into the intriguing topic of shapes that are both rectangles and squares. While many might think these terms are synonymous, there is a subtle yet critical difference between the two. Let’s explore which shape exhibits both qualities.

## The Rectangle

**A rectangle** is a quadrilateral with four right angles. In simpler terms, all its angles are 90 degrees. This geometric figure has opposite sides that are equal and parallel. Rectangles are commonly found in everyday objects such as books, doors, and windows. The formula for calculating the perimeter of a rectangle is P = 2(l + w), where l is the length and w is the width. The area of a rectangle is given by A = l * w.

## The Square

**A square** is a special type of rectangle where all four sides are equal in length. In essence, a square is a rectangle with additional properties. Square shapes have four right angles like rectangles, but they exhibit symmetry along all axes. Squares are versatile and commonly used in various fields, including art, architecture, and mathematics. The formula for finding the perimeter of a square is P = 4s, where s is the length of one side. The area of a square is calculated as A = s^{2}.

## The Square That Is Also A Rectangle

At this point, you might be wondering which shape falls into both the rectangle and square categories. The answer is simple yet profound – **a square is also a rectangle**. Given the definitions we discussed earlier, it becomes evident that a square meets all the criteria of a rectangle and then some. Let’s break down the key characteristics that make a square a rectangle:

- All angles are right angles (90 degrees).
- Opposite sides are parallel and equal in length.
- Has all the properties of a rectangle with the additional feature of equal side lengths.

Therefore, a square encompasses all the defining traits of a rectangle, making it a special case within the broader category of rectangles.

## Conclusion

In conclusion, the shape that is both a rectangle and a square is **the square itself**. While rectangles and squares share similar characteristics, a square is a more specific form of rectangle with additional properties such as equal side lengths. Understanding the distinctions between these shapes is essential for grasping geometric concepts and solving mathematical problems. Next time you encounter a square, remember that it is not just a square – it’s also a rectangle!
