NCERT Solutions for Class 9 Maths, Chapter 12 - Heron's Formula

In earlier classes, you have studied different shapes and figures in detail and have learnt how to find out the areas and perimeters of squares, circles, triangles, quadrilaterals and other geometrical figures. In this chapter, you’ll study about Heron and his formula. This chapter talks about Heron, a famous mathematician, and his contributions in the field of mathematics and physics. He derived very important formulae related to areas and volumes of squares, triangles, rectangles, trapezoid. In NCERT Solutions for Class 9 Maths, Chapter 12, you’ll study Heron’s formula for the area of a triangle with respect to its three sides.

Let’s take a look at Class 9 Maths, Chapter 12 – HERON’S FORMULA

12.1 Introduction

12.2 Area of a Triangle – by Heron’s Formula

12.3 Application of Heron’s Formula in finding Areas of Quadrilaterals

12.4 Summary

In Class 9 Maths Chapter 12, you will learn – 

Section 12.2 – In this section, you’ll learn about the formula proposed by Heron to find the area of a triangle – known as the Heron’s Formula. This formula is very useful in situations when the height of the triangle is not available easily.

 Section 12.3 – In this section, you’ll study how to apply Heron’s formula in finding the areas of various Quadrilaterals. The Quadrilaterals are divided into triangular parts and then, the Heron’s formula is used to find the area of each triangle.

All the concepts in this chapter are explained thoroughly with numerous solved examples for better understanding.
