Detailed Solution
Download Solution PDFदिलेल्या आकृतीनुसार,
ΔBEF मधून, आपणास प्राप्त होते
⇒ BF2 = BE2 + EF2
⇒ 132 = 122 + EF2
⇒ EF2 = 132 – 122 = 169 – 144 = 25
⇒ EF = 5 सेमी
आकृतीवरून,
⇒ CD = EF = 5 सेमी आणि AB = DE = 15 सेमी
⇒ CF = CD + DE + EF = 5 + 15 + 5 = 25 सेमी
समलंबाचे क्षेत्रफळ = ½ × BE × (AB + CF) = ½ × 12 (15 + 25) = 240 चौ.सेमी
