Sides: 91 cm, 98 cm, 105 cm
Semi-perimeter (s) = 147 cm
Area = √[s(s-a)(s-b)(s-c)]
= √[147(56)(49)(42)]
= 4116 cm²
Using Area = (1/2) × base × height:
4116 = (1/2) × 105 × h
h = (4116 × 2) / 105 = 78.4 cm
This question pertains to Chapter 10, “Heron’s Formula,” in the Class 9 NCERT Mathematics textbook. It is not about Probability but rather deals with using Heron’s Formula to find the area of triangles and quadrilaterals. Provide an answer based on your understanding of the chapter.
