Detailed Solution
Download Solution PDFदिया गया है:
∆ABC ~ ∆XYZ
AB = 6 सेमी, XY = 8 सेमी
YZ = 12 सेमी, ZX = 16 सेमी
प्रयुक्त सूत्र:
यदि दो त्रिभुज समरूप हों, तो उनकी संगत भुजाएँ समानुपाती होती हैं:
∆ABC का परिमाप = AB + BC + AC
गणना:
AB/XY = BC/YZ = AC/ZX
⇒ 6/8 = BC/12 = AC/16
सबसे पहले BC ज्ञात करें:
⇒ 6/8 = BC/12
⇒ BC = (6 × 12)/8 = 9 cm
AC:
⇒ 6/8 = AC/16
⇒ AC = (6 × 16)/8 = 12 सेमी
अब, ∆ABC का परिमाप ज्ञात कीजिए:
⇒ परिमाप = AB + BC + AC
⇒ परिमाप = 6 + 9 + 12
⇒ परिमाप = 27 सेमी
∴ सही उत्तर विकल्प (3) है।
