Explain How to Find the Area and Perimeter of a Rectangle

A rectangle is a four-sided polygon with all internal angles of 90 degrees. Every corner, or vertex, has two sides that meet at right angles. The rectangle differs from a square in that its opposite sides are of similar length. A very widely used example is that if one side of a rectangle is 12 cm long, the opposite side is also 12 cm long.

A rectangle is a quadrilateral with parallel sides which are equal to one another and all four vertices that are 90 degrees. As a result, it’s also known as an equiangular quadrilateral. Since the opposite sides of a rectangle are identical and parallel, it is also known as a parallelogram.

What is the Shape?

A rectangle is a two-dimensional flat shape of two dimensions. We can easily represent a rectangle in an XY plane by using the arms of the x-axis and the y-axis to indicate the length and width of the rectangle, respectively.

The Perimeter of the Rectangle:

The diameter of a rectangle is the length of the rectangle’s outer boundary. It is equal to the number of the rectangle’s total length and width measurements. In our daily lives, we use the circumference of a rectangle to calculate distances and lengths. The perimeter of the rectangle is the cumulative distance protected by the rectangle’s outer boundary. It is counted in units of time. The perimeter formula is as follows: Perimeter, or also written as P = 2 (Length + Width)

Types of Rectangles

A rectangle is a two-dimensional geometry with four sides, opposite sides that are identical, and adjacent sides that cross at 90 degrees. Two equal diagonals make up a rectangle. The diagonals’ length is determined by multiplying their length and width. Rectangles are divided into two types:

  • Square
  • Golden Rectangle
Area of Rectangle

The number of unit squares that can fit into a rectangle is called its area. The flat surfaces of desktop monitors, blackboards, painting canvas, and other rectangular shapes are examples. The region of a rectangle formula can be used to calculate the space occupied by these objects. The region covered by a two-dimensional shape in a plane is considered as the area of the rectangle. It is based on square units of measurement. As a result, the rectangle’s area is equal to the area enclosed by its outer boundaries. It equals the sum of the length and width.

The area of the rectangle formula is expressed as: A = wl, where “w” is the width and “l” is the provided length of the respective rectangle.

Properties of a Rectangle:

According to the characteristics and properties you can understand the composition of a rectangle more easily:

  • It has exactly four sides and four vertices or corners.
  • Every vertex has an angle equal to precisely 90 degrees.
  • The opposite sides of the rectangle are invariably equal and parallel.
  • Diagonals bisect each other in the center of the rectangle.
  • The perimeter is similar to twice the sum of the respective rectangle’s length and breadth.
  • The area is similar or equal to the product of the rectangle’s length and breadth
  • A rectangle is a parallelogram that consists of four right angles.
  • The total sum of all interior angles is exactly 360 degrees.
The Diagonals of the Rectangle:

A rectangle’s diagonal is a line segment connecting any two of its non-adjacent vertices. The diagonals in the following rectangle are AC and BD. As you can see, the lengths of AC and BD are identical. A diagonal divides a rectangle into two right triangles, each with sides identical to the rectangle’s sides and a hypotenuse. The diagonal is the hypotenuse.

What is a Golden Rectangle?

A golden rectangle is a rectangle with a length-to-width ratio of 1: (1+ 5)/2, which is identical to the golden ratio.
