Any figure with four sides and four right angles is known as a rectangle (90 degree angles). You can see them anywhere in the globe if you look around. The room you’re in most likely consists of several rectangles or rectangles in some other shape. It is a straightforward shape that is simple to use.
When you first drew a house as a child, you most likely also drew a rectangle. Most doors that you see have what shapes? They’re rectangles, right? Consider windows. They all have four sides, right angles, correct?
There are specific characteristics that all rectangles must exhibit, in addition to having four sides and four 90-degree angles.
What are the Real Life Uses of a Rectangle:
1. Laptops
A laptop has four sides, with the opposite sides being parallel to one another and having equal lengths. As a result, a laptop stands out as a common example of a rectangle-shaped device in everyday life. The keyboard and a monitor’s screen are both rectangular objects in a similar way.
2. Mobile devices
Another example of a rectangular-shaped object utilised in daily life is a cell phone or mobile phone.
3. Door
Door Most of the time, a door’s length is kept longer than its width.
4. Chocolate Bar
The shape of a chocolate bar is rectangular. So the next time you consume a chocolate bar, remind yourself of what a rectangle is and its characteristics. So the next time you consume a chocolate bar, remind yourself of what a rectangle is and its characteristics.
5. Tabletop
Take a look at the tables you have at home or at work. It might be used as a computer table, a study table, or a dining table. You’ll notice that the majority of them have rectangular shapes.
6. Bed
Bed But when two of these beds are put together, the rectangular shape frequently changes to a square.
7. The Curtain
Most curtains are shorter in the horizontal direction and substantially longer in the vertical direction. A curtain’s horizontal and vertical sides are also parallel to one another. The best example of a rectangle-shaped object in the real world is a curtain.
Examples of Rectangles:
Doors, windows, and books are just a few of the common examples of rectangles that have been mentioned. In the picture below, locate the rectangles!
This physical sciences classroom is filled with rectangles.
A shape with four sides and four right angles is what you should be looking for. The windows in the background, the ceiling tiles, the laptop computer, the notebooks in front of the students, and last but not least, the tables at which the students are seated, are all visible. These are just a few instances of the numerous rectangles that can be seen throughout daily life.
Importance of Rectangles:
Right angles form where its two sides meet. As a result, a rectangle has four 90° angles. A rectangle’s opposing sides are parallel and the same length. When the distance between two sides remains constant throughout, they are considered to be parallel.
Rectangle’s perimeter
The complete distance that the rectangle’s outside boundary covers is referred to as its perimeter. Its length is expressed in units. Perimeter, P = 2 (Length + Width), is the definition of perimeter.
Properties of a Rectangle
1. A rectangle has four interior angles that are all exactly 90 degrees.
2. A rectangle’s opposite sides are parallel and equal to one another.
3. When the length is expressed as the square root of the sum of the squares of length and width, the diagonals created by joining the opposing corners of the quadrilateral are equal in length.
4. A rectangle’s diagonals cut each other in half.
Example:
Calculate the area and perimeter of a rectangle whose length and width are 14 cm and 10 cm, respectively.
Solution:
Rectangle attributes can be used to determine a rectangle’s area and perimeter. The rectangle measures 14 cm in length and 10 cm in width.
Area of a rectangle: 14 x 10 cm2 (length x width).
A rectangle’s perimeter equals 2 (length plus width).
2 (14 + 10) = 24 × 2 = 48 cm
2 (14 + 10) = 24 × 2 = 48 cm
Conclusion
In geometry, a rectangle is a 2D form with 4 sides and 4 corners. Right angles form where its two sides meet. As a result, a rectangle has four 90° angles. A rectangle’s opposing sides are parallel and the same length.
