Download Solution PDFΔABC में, D, AB पर एक बिंदु इस प्रकार है कि BD = 3 सेमी और DA = 4 सेमी।E, BC पर एक ऐसा बिंदु है कि DE || AC है। तो ΔBDE का क्षेत्रफल : समलंब ACED का क्षेत्रफल
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFदिया गया है:
BD = 3 सेमी
DA = 4 सेमी
प्रयुक्त अवधारणा:
समानता की अवधारणा
गणना:
यहां ΔABC ∼ ΔBDE [∵ DE || AC और B दो त्रिभुजों के लिए उभयनिष्ठ हैं]
इसलिए,
ΔABC/ΔBDE = 72/32
⇒ ΔABC/ΔBDE = 49/9
ACED = ΔABC - ΔBDE
⇒ 49 - 9 = 40
∴ अनुपात 9 : 40 है
∴ तो ΔBDE का क्षेत्रफल : समलम्ब ACED का क्षेत्रफल 9 : 40 है
