Heron's Formula in ONE SHOT | 2023- 24 | Chapter 12 | Easy Explanation | Class 9

[@ridhdham]

this is my homework EX 1:Find the area of a triangle, two sides of which are 8 cm and 11 cm and the perimeter is 32 cm ANSWER:√16 8 5 3 cm =√8 30 cm EX 2:A triangular park ABC has sides 120m, 80m and 50m (see Fig. 12.7). A gardener Dhania has to put a fence ....one side. ANS:375√15 m² and the cost is 4940 rupees! EX 3 : The sides of a triangular plot are in the ratio of 3 : 5 : 7 and its perimeter is 300 m. Find its area. ANS : 1500 √3 m² THATS ALL I PRACTICED.. THANK YOU MAAM!!

[@2aa7]

First question doesn't have to be so hard, because the value of the perimeter is already given in the question. Instead do this: Perimeter = 180 cm a = 180/3 = 60 cm s = P/2 = 180/2 = 90 cm using heron's formula, √90(90-60)(90-60)(90-60) =√90*30*30*30 simplifying that we get =√3*3*2*5*3*2*5*3*2*5*3*2*5 =3*2*5*3*2*5√3 =900√3cm^2

900 underoot 3^2 = 900 * 3 = 2700
