  1. Longest side = 42 cm
    Semi-perimeter (s) = 48 cm
    Area = √[s(s-a)(s-b)(s-c)]
    = √[48(6)(14)(28)]
    = 336 cm²

    Using Area = (1/2) × base × height:
    336 = (1/2) × 42 × h
    h = 336 / 21 = 16 cm
    This question related to Chapter 10 Mathematics Class 9th NCERT. From the Chapter 10 Heron’s Formula. Probability. Give answer according to your understanding.
