In earlier classes, we have learned about various plane figures such as triangles, quadrilaterals, squares, rectangles etc. We also learned the formula for finding the perimeters and areas of a square, a rectangle, and some specific triangles. In this, RD Sharma Solutions for class 9 maths chapter 12 we will learn about the famous Heron’s formula which is used for finding the area of a triangle in terms of its three sides. Suppose if a, b, c denote the lengths of the sides of a triangle ABC. The area of triangle

\(\sqrt{s(s-a)(s-b)(s-c)}\)

Further, we will discuss some applications of Heron’s formula. For example, if a landowner needs to find out the area of his land which is in the shape of a quadrilateral. He needs to divide the quadrilateral into triangular parts and use the heron’s formula for the area of a triangular part. Learn to apply heron’s formula easily by understanding the practice problems that are solved in RD Sharma solutions given below.
