ΔABC ~ ΔPQR
ΔABC এর ক্ষেত্রফল = 64 সেমি2
ΔPQR এর ক্ষেত্রফল = 81 সেমি2
PT = 10.8 সেমি
AD হল ΔABC এর মধ্যমা
PT হল ΔPQR এর মধ্যমা
ধারণা:
দুটি অনুরূপ ত্রিভুজের ক্ষেত্রফলের অনুপাত সংশ্লিষ্ট বাহু ও মধ্যমার বর্গক্ষেত্রের অনুপাতের সমান।
ar(ΔABC)/ar(ΔPQR) = AD2/PT2
⇒ 64/81 = AD2/PT2
⇒ √64/81 = AD/PT
⇒ 8/9 = AD/10.8
∴ AD = 9.6 সেমি
