NCERT Solutions for Class 9 Maths Chapter 12 Exercise 12.1: Chapter Description

NCERT Class 9 Maths Chapter 12 Exercise 12.1 deals with the concept of Heron’s Formula in Mathematics. Heron’s Formula has a lot of significance in Geometry because we can find the area of a triangle when the measurement of the three sides is given. This chapter starts with finding the area of a triangle using Heron’s Formula with the help of different examples. The chapter also introduces other concepts related to the area of the triangles. Through this chapter, students will learn the application of Heron’s Formula to find the area of quadrilaterals. The area of a quadrilateral whose side lengths and one diagonal are given can be calculated by dividing the quadrilateral into triangles and using Heron’s Formula to find the area. The application of Heron’s Formula happens in various situations in everyday life, such as outdoor geometries.

The following are the other exercises in the chapter along with the number of questions in it:
