দুটি সদৃশ ত্রিভুজের ক্ষেত্রফল যথাক্রমে 324 সেমি2 এবং 289 সেমি2
অনুসৃত ধারণা:
দুটি ত্রিভুজ সদৃশ হলে তাদের ক্ষেত্রফলের অনুপাত তাদের সংশ্লিষ্ট বাহুর অনুপাতের বর্গের সাথে সমানুপাতিক
\({Area ~\triangle(ABC)\over {Area ~\triangle(DEF)}} = {[corresponding ~height~\triangle(ABC)]^2\over{[corresponding ~height~\triangle(DEF)]^2}}\)
গণনা:
ধরি △ ABC-এর সংশ্লিষ্ট উচ্চতা = H1
এবং △ DEF-এর সংশ্লিষ্ট উচ্চতা = H2
⇒ \({Area ~\triangle(ABC)\over {Area ~\triangle(DEF)}} = {[corresponding ~height~\triangle(ABC)]^2\over{[corresponding ~height~\triangle(DEF)]^2}}\)
⇒ (H1)2/(H2)2 = 324/289
⇒ H1/H2 = √324/√289
⇒ H1/H2 = 18/17
∴ সঠিক উত্তর 18/17
