Detailed Solution
Download Solution PDFপ্রদত্ত:
AB = 4 সেমি, PQ = 6 সেমি, QR = 9 সেমি এবং RP = 12 সেমি
গণনা:
ΔPQR এর বাহুগুলির অনুপাত হবে
⇒ 6 : 12 : 9 = 2 : 4 : 3
যেহেতু \(\triangle \mathrm{ABC} \sim \triangle \mathrm{PQR}\)
সুতরাং, বাহুগুলির অনুপাত একই হবে।
⇒ 2 একক = 4
⇒ 1 একক = 2
⇒ 2 × 2 : 4 × 2 : 3 × 2
⇒ 4 : 8 : 6
ΔABC এর পরিসীমা = (4 + 8 + 6) = 18
∴ সঠিক উত্তরটি হল 18 সেমি।
