Area of a trapezoid: RS Aggarwal Class 8 Solutions Chapter 18 An Overview
The trapezium is a closed two-dimensional shape with two sides that run parallel to each other. It has four sides and four points where they meet. The parallel sides of a trapezium are called bases, and the sides that aren’t parallel are called legs. Basic concepts:
- The bases of a trapezium are the sides that are parallel, and the legs are the sides that are not parallel.
- A line drawn from where two sides that don’t go in the same direction meet is the midpoint.
- In the diagram, the arrows and equal signs show that the lines are parallel and that the lengths of each side are the same.
- If you cut the trapezium in half from the middle of the two sides that aren’t parallel, you’ll get two pieces that aren’t the same size.
- A trapezium with two sides that don’t go in the same direction is called an isosceles trapezium. It has two sides that don’t go in the same direction.
How to Figure Out the Area of a Trapezium
Half of the sum of a trapezium’s parallel sides and height is its area. The area of a trapezium is equal to 12 times the sum of the lengths of the parallel sides times the distance between them. This is written as 12(b1+b2)h.
The idea of a trapezium can be used in many different ways. In physics, it is used to answer questions about trapezoids. In mathematics, it is used to answer questions about surface area or find a complex figure’s area or perimeter. The trapezoid formula can also be used in building since the shape of the roof is a trapezoid. It can be used for many things in everyday life.

RS Aggarwal Class 8 Solutions Chapter 18
After you finish solving the problems in this chapter of the NCERT math book, move on to Class 8 RS Aggarwal Chapter 18. Most of the time, students do this to learn more about this topic and get used to different kinds of questions.
In the first exercise, the questions will test how well you know how to use the formulas from this chapter. In the first set of questions, you will be asked to figure out the area of trapezoids by just changing the numbers in the formula. As you go on, you’ll have to set up an equation to find the unknown number in the questions. To figure out how to answer these questions by making the right equations, you will need to focus on learning the formulas. This will help you replace the term with a variable and make an equation. Follow the RS Aggarwal Solutions for Class 8 Chapter 18 to learn how to make the answers easily.
During the same activity, the hints will get more important. To see what the problem is, you will need to focus on drawing the hints into a geometric shape. It will make it easy for you to solve the problem. Experts say that half of the time, you can solve a geometric problem by drawing a picture. If you look at the RS Aggarwal Class 8 Solutions Chapter 18, you’ll see that the teachers have used a diagram in a clever way to help you understand the problem and explain how to solve it.
In the next exercise, you will be asked questions about quadrilaterals and polygons. In this case, the shapes might or might not be regular. You’ll need to pay attention to how to use the basic formulas you learned in the last chapter and in this one. Most polygon problems will require you to use the formulas for figuring out the areas of triangles. Start with one problem at a time and use RS Aggarwal Class 8 Solutions Chapter 18 to help you figure out the answers.
You’ll also notice that the formulas or expressions used to figure out the area of a polygon are getting harder to understand. Pay close attention to each word in the phrase to make sure you don’t make a mistake.
In the next exercise, you’ll be asked questions that remind you of all the formulas you’ve learned about the areas of different triangles, rhombuses, and parallelograms. Recognize the geometric shapes and get the hints so you can use these formulas correctly. In RS Aggarwal Class 8 Solutions Chapter 18, all the area-based formulas are reviewed and new ones are taught.
FAQ ( Frequently Asked Questions )
1. What are the benefits of using RS Aggarwal Solutions Class 8 Chapter 18?
Ans – In the solutions PDF, our teachers show and explain how to solve the critical sums in RS Aggarwal Solutions for Class 8 Chapter 18 in the easiest and simplest ways. When you know the tricks and tips, it’s easier to figure out how to do these sums. You can use the PDF of this solution as a guide while practicing the sums in this chapter to help you understand them better.
One of the best things about doing RS Aggarwal Class 8 Solutions Chapter 18 questions is that you learn things that aren’t on the regular curriculum. The exercises have different kinds of questions that help the students understand the ideas in detail and in-depth.
2. Is it important to use reference books to study for the Class 8 School exam?
Ans – If you’ve done all the exercises in the Class 8 NCERT Maths book and thought carefully about how to answer the example questions, you can start using reference books. These books are for students who are ready for more difficult work. Reference books are helpful because they let you try out different kinds of questions. So, if you want to make sure you know everything you need to know for your test, reference books are the way to go!
3. What are the different kinds of trapeziums in Class 8 Math?
Ans – A trapezium is a closed, two-dimensional shape with two sides that run parallel to each other. It has four sides and four points where they meet. The parallel sides of a trapezium are called bases, and the sides that aren’t parallel are called legs. There are three main kinds of trapeziums:
- The Scalene Trapezium has different-sized sides and angles.
- Isosceles Trapezium: A trapezium isosceles if any two pairs of sides, such as the bases or legs, are the same length.
- Right Trapezium: A right trapezium has at least two right angles, which are 90°.
