    Here,
    Given-
    It is an equilateral triangle
    Therefore, 3a=180
    Therefore, a=60
    We know,
    a= side
    Now semi perimeter=
    180/2= 90
    Therefore, area=
    √(90*(90-60) *(90-60) *(90-60) )
    =√90*30*30*30
    =900√3
    Maturity is Reasiling that we don't need to do this like that!

    Guys!!! This was my second favourite chapter in class 9th , because first was surface, areas and volumes , I am now in class 10th , so guys , I am giving you some advice , no one asked me but still I'm a headache so I will tell , so these are :
    1. Focus on a little tough chapters like quadrilaterals , circles , triangles , polynomials ( polynomial is an easy chapter , but some of my former classmates does not like it , so just in case)
    2. Please practice some other books like ncert exampler , rd Sharma , rs Aggrawal ( any one reference book is needed , not every book , but if you are a bookworm ,then you can practice all of it )
    3. practice ncert examples too , and if you have enough time , then solve the old syllabus of the book ( because my school included old syllabus in the final exam , I had not practiced it much , but still I managed , but some of my former classmates were not able to solve the paper , so they got less marks compare to mine , but if your school is good ,then it is totally fine ,you don't have to practice it)
    4. Pay attention to the classes , if you cannot pay attention ,then watch that question on UA-cam or any app , and practice daily
    5. Ask your maths teacher to give you a weekly or monthly test for preparation , then by this you can get to know how your teacher makes question paper , so the question paper can be familiar
    6. Collect previous year question paper from your seniors , then try to solve it in your free time , then you would have a good practice
    7. In exam , leave MCQs and then solve whole paper and then start to solve the MCQs , because it takes so much time.
    So these are my advices , I know that many would not read it , and after the finals they will regret it , because 9th class paper is so much tough , and there will be strict checking , half of my class failed 9th class , so please try to follow atleast 3 of them , if you do not have reference book ,then you have google , search it , if you can't find it then simply search extra questions of the chapter , then you would get so many questions , ok
    WARNING ⚠️ = DO NOT TRUST NCERT BOOK AND YOUR TEACHERS , BECAUSE I REGRETTED IT
    Ok so that was pretty enough , and don't think that I failed my 9th class because I got 72/80 in maths , so give the best of you , because if you failed , your teachers will make your life hell and parents too , Ok , also wish me because this year I have boards 😭

    Sir actually u did a little mistake u have to multiply by 3. Since it's an equilateral triangles so 180÷3 = 60

      Ya bro i was asking the same that this ques can be do like this :-
      Given that
      Sides of equilateral triangle = a
      Perimeter = 180 cm
      So, S = half of the perimeter
      = a + a + a = 180cm
      = 3a = 180 cm
      = a = 180/3 = 60°
      Then ,
      S = a + b + c/2
      S= 60 + 60 +60/2
      S = 180/2 = 90°
      Area of triangle = √ s(s-a) (s-b) (s-c)
      = √90(90-60)(90-60)(90-60)
      =√90×30×30×30
      =√3×3×10(3×10)(3×10)(3×10)
      =3×3×10×10√3
      =900√3 cm²
