Detailed Solution
Download Solution PDFदिलेले आहे:
BD = 3 सेमी
DA = 4 सेमी
वापरलेली संकल्पना:
समानतेची संकल्पना
गणना:
येथे ΔABC ∼ ΔBDE [∵ DE || AC आणि ∠B दोन त्रिकोणांसाठी सामान्य आहे]
तर,
ΔABC/ΔBDE = 72/32
⇒ ΔABC/ΔBDE = 49/9
ACED = ΔABC - ΔBDE
⇒ 49 - 9 = 40
∴ गुणोत्तर 9 : 40 आहे
∴ ΔBDE चे क्षेत्रफळ : समलंब ACED चे क्षेत्रफळ 9 : 40 आहे.
