Class 10 Chapter 17 - Perimeter and Areas of Plane Figures- Overview

Chapter 17 of Class 10 from R S Aggarwal deals with Perimeter and Areas of Plane Figures. This exercise contains 67 problems. Answers to these questions have been carefully formulated by our experts at Vedantu. This is done after carefully referring to standard books and credible sources. Students have to solve all the problems to improve their marks in the board exams. 

Students are recommended to answer the questions themselves before reading the solutions. Answered questions can be cross-checked with the solutions provided. This will develop the logical thinking skills of the students. Solving complex problems will strengthen the basics and also help students to grasp the complex problems and concepts in the future easily. Following are the concepts dealt with in this chapter:

  • Area of a quadrilateral 

  • Area of an equilateral triangle 

  • Area of a rhombus 

  • Area of a trapezium 

  • Area of an isosceles triangle 

  • Area of a rectangle 

  • Area of a square etc.

FAQs on RS Aggarwal Solutions Class 10 Chapter 17 - Perimeter and Areas of Plane Figures (Ex 17A) Exercise 17.1

1. What is a quadrilateral and what are the different types as mentioned in Chapter 17 Class 10 of RS Aggarwal?

Quadrilateral is a closed polygon with four sides. It is of different types like a square, rectangle, rhombus, parallelogram. It is divided based on the lengths of the sides and angles between two line segments. For example, the length of all sides in a square are equal but for a rectangle, the length of opposite sides are equal. In a parallelogram, opposite sides of the quadrilateral are parallel to each other. You can find the solutions and explanations for this chapter and all the other chapters from this book on Vedantu’s RS Aggarwal Class 10 Maths Solutions.

2. What is an equilateral triangle and how to measure the area and perimeter of it as mentioned in Chapter 17 Class 10 of RS Aggarwal?

Equilateral triangle is a type of triangle with all three sides having equal lengths. As they have equal lengths, all the angles also measure the same. Every angle in an equilateral triangle measures 60 degrees. The area of an equilateral triangle is measured by the formula:

  • \[A=\frac{\sqrt{3a^{2}}}{4}\]

Here “A” represents an area of an equilateral triangle

“a” represents the base length of the equilateral triangle. 

  • The perimeter of the equilateral triangle is measured by P = 3a

P represents perimeter and a represents the length of the side which is equal for all three sides. 

3. Should a student compulsorily practice from the  RS Aggarwal books for the Class 10 board exam?

R S Aggarwal is a great book for practicing Mathematics for Class 10 students. It has questions to solve chapter-wise and solutions for the same. This book is in perfect sync with the CBSE syllabus, curriculum, and exam pattern. Students are recommended to answer the questions themselves before reading the solutions. Answered questions can be cross-checked with the solutions provided. Although it is not compulsory to go through the book for the Class 10 Board exams, once you finish your NCERT syllabus, you may go through it to get the required practice for the exam.

4. What is an isosceles triangle and how to measure its area and its perimeter as mentioned in Chapter 17 Class 10 of RS Aggarwal?

An isosceles triangle is a triangle in which two of its sides are equal in length. So the angles opposite to the sides with the same length also measure the same. 


Formula to measure the area of an isosceles triangle:

  • A = ½ × b × h

A is the area of the triangle

B is the length of the base

H is the height of the triangle


Formula to measure the perimeter of the triangle is:

  • P = 2a + b

P is the perimeter

a is the length of the side (two sides are similar in an isosceles triangle)

B is the length of the third side of the triangle 

5. What is a rhombus and how to measure its area as mentioned in Chapter 17 Class 10 of RS Aggarwal?

A rhombus is a type of quadrilateral with four equal sides and all the angles of the rhombus are congruent. 

Formula to measure the area of a rhombus is:

  • Measuring the area of a rhombus using the diagonals: A = ½ × d1 × d2

 D1 is the length of the diagonal 1 and d2 is the length of the diagonal 2

  • Measuring the area of a rhombus using base and height: A = b × h

Here, b represents  the base length and h represents the height of the triangle

Formula to measure the perimeter:

  • P = 4a where “P” is the Perimeter and “a” is the length of the side
