Measuring length & areas of Shapes

Geometry is among the most significant subjects in Mathematics that deals with various shapes, such as rectangles, squares, and others. It helps us to understand the various features associated with these types of shapes. They are utilized in solving problems related to various topics like trigonometry math, algebra, calculus, and more. In this blog, we’re exploring the shape of a rectangle. We will learn how to determine the dimensions of an area and also calculate the perimeter of the rectangle. However, first, let’s start with some basic concepts.

What is a Rectangle?

A rectangle is a 2D geometric shape with four sides as well as four vertices, or corners. A rectangle’s opposite edges are the same length and are parallel to one another, i.e., all the points are equal. The edges of the rectangle cross each and form an angle known as a right angle. The two sides that are larger are referred to as”the length” of the rectangular and the smaller side is known as the width of the rectangle.

The word”rectangle” originates from the Latin word rectangular meaning right angle. The rectangle is among the easiest shapes to study however, questions pertaining to a rectangle within concepts such as Trigonometry and Calculus may be complicated. It is therefore essential to be able to comprehend the fundamentals. With the assistance of Cuemath online classes for learning You can learn about the various geometric shapes with visual simulations that can help you tackle complex problems that are related to rectangles in the near future.

How to Find the Perimeter of a Rectangle?

To determine the dimensions of a rectangle we need to measure all sides. After you’ve taken measurements of all the sides, you need to add them all up. After adding all sides, the result we get is the circumference that is the size of the rectangle.

For example, a rectangle of length 15cm and width 10cm, if we could apply this formula: 2 (l+b) and get 2(15+10), i.e 2(25)= 50. Thus, the radius of the rectangle measures 50cm.

The length of the Rectangle

The length of the rectangle is the sum of all the sides of the rectangle. Since opposing sides of rectangles are the same the rectangle’s perimeter will be twice that of the rectangular and twice the width of a rectangle.

If p is the perimeter of the rectangle, l represents the length, while it is b the width then the perimeter could be described in the form of the equation by :

The formula P = 2l+2b is ( l+b)

Therefore the equation (l+b) is the definition of the perimeter. In this equation, l and b represent the width and length of the rectangle and vice versa.

Area of the shape

The area occupied by the rectangle within the 2D space is called the Area of the shape. The term “area” is the sum of the length and width of the rectangular. Therefore, the formula for the rectangle’s area is as follows: A = l*b. The rectangle’s area can be measured by squares.

Steps to Find the Area of a Rectangle

In addition to the rectangle as well, the size of a parallelogram may be determined by using its height and base. Multiply the height and base or make use of an area calculation using the calculator for parallelograms.

Step 1: Prior to starting to work, you must change the dimensions of breadth and length in the database. They should be in the same units.

Step 2: Once you have converted the units, use the formula for the size of an elongated rectangle. i.e. L*B. When you multiply the length with the breadth, you will get the answer you want.

Step 3: Keep in mind that the final answer must have square units.

For instance example, in a rectangle that has an area of 6cm in length and length of 5cm, the total area is l*b. i.e. 6*5= 30cm2.
