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 KZbin 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 😭
