Frequently Asked Question (FAQs)

Q1. List all the essential formulas required to Solve class 7 Chapter - Area and Perimeter Mathematical Problems.

Ans. Below are the formulas for the Area and Perimeter of some standard polygons. Students should practice questions that will automatically allow them to retain the formulas in their examinations.

Given below are the essential formulas for some standard polygons.

• Area of the rectangle= l X b

where l is length and b is breadth

Perimeter of a rectangle = 2(l+b)

Area of Square=a ²

Where a is the side of a square

Perimeter of square=4a

• Area of Circle = πr ²

For a circle with a radius “r.”

Circumference of Circle=2πr

• Area of triangle=1/2 X b X h

Where b is base and his height

The perimeter of the triangle= Sum of all sides of the triangle

• Area of an equilateral triangle = √3a ² /4

where a is the side of an equilateral triangle

The perimeter of an equilateral triangle = 3a

Q2.How can I get benefits from solving Maths Important Questions?

Ans. The exam pattern is divided into sections A, B, C, and D. To solve the questions in each area, you need to practice many questions regularly. Familiarizing yourself with essential questions will help you become familiar with the type of questions. If you know the concepts well, you can solve straightforward questions quickly.

To solve word problems, you need to convert them into problems that can be solved first before you try. Familiarizing yourself with important questions will give you the confidence to solve any difficult question that comes in your exam.

Another way to practice the important questions in each chapter is to solve paper samples. Solving the sample papers within the allotted time will benefit you because you will be familiar with working under the pressure of time. Focus on understanding the concept of the critical questions and the pattern they follow.

Q3. What is the difference between area and perimeter?

Ans. The perimeter of a closed figure is the distance around it, and its area is the fraction of the plane or region it has installed. A regular polygon parameter is equal to the number of sides multiplied by the length of one side. Generally, the perimeter and area of ​​various forms vary and are calculated using different formulas based on this concept.

Perimeter and area are important mathematical concepts and weigh important in the exam. You can prepare well with Physics Wallah.

Q4. What is an irregular shape?

Ans. Any size and length are possible in an irregular form. Kite, diamond shapes, leaves, and other unusual types can be seen around us. The irregular form is defined as sides and angles that do not have the same length. Stones, prisms, beans, and screws are examples of irregular solid that are rare.

Each object has a unique irregular form that is not built on common conditions. Difficulty measuring and unusual solid surface, volume, or weight by measuring its length, width, and height separates it.

Q5. What is the difference between irregular and regular shapes?

Ans. The irregular form can be of any size and length, and the standard shape has equal sides and angles. Thus, the area of a regular shape can be calculated directly using the correct formula. Still, the  ​​irregular shape can be calculated by rotting the abnormal state into many common ones.

Areas of irregular shape are often difficult to calculate due to their unpredictability. Therefore, a different approach than normal when calculating the area of regular shapes should be considered irregular shapes.
