Download Solution PDFदिलेल्याप्रमाणे:
ΔABC आणि ΔDEF हे समान त्रिकोण आहेत आणि त्यांचे क्षेत्रफळ अनुक्रमे 49 सेमी2 आणि 144 सेमी2 आहेत.
EF = 16.80 सेमी
वापरलेली संकल्पना:
जर दोन त्रिकोण सारखे असतील, तर दोन्ही त्रिकोणांच्या क्षेत्रफळाचे गुणोत्तर त्यांच्या संबंधित बाजूंच्या गुणोत्तराच्या वर्गाच्या प्रमाणात असते.
गणना:
ΔABC आणि ΔDEF समान त्रिकोण असल्याने,
⇒
⇒ BC = 7/12 × 16.80
⇒ BC = 9.8
∴ BC ची लांबी 9.8 सेमी आहे.
